+# Differential Gaussian Rasterization
+
+**NOTE**: this is a modified version to support depth & alpha rendering (both forward and backward) from the [original repository](https://github.com/graphdeco-inria/diff-gaussian-rasterization). 
+
+```python
+rendered_image, radii, rendered_depth, rendered_alpha = rasterizer(
+    means3D=means3D,
+    means2D=means2D,
+    shs=shs,
+    colors_precomp=colors_precomp,
+    opacities=opacity,
+    scales=scales,
+    rotations=rotations,
+    cov3D_precomp=cov3D_precomp,
+)
+```
+
+
+Used as the rasterization engine for the paper "3D Gaussian Splatting for Real-Time Rendering of Radiance Fields". If you can make use of it in your own research, please be so kind to cite us.

For example, the lookAt function generates a transform from world space into the specific eye space that the projective matrix functions (perspective, ortho, etc) are designed to expect. The OpenGL compatibility specifications defines the particular layout of this eye space.</p>

+#
+# All text after a double hash (##) is considered a comment and is placed in
+# front of the TAG it is preceding.
+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:
+# TAG += value [value, ...]
+# Values that contain spaces should be placed between quotes (\" \").
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
+

+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
+# double-quotes, unless you are using Doxywizard) that should identify the

+## <a name="section1"></a> 1. Getting started
+
+### <a name="section1_1"></a> 1.1. Using global headers
+
+GLM is a header-only library, and thus does not need to be compiled. We can use GLM's implementation of GLSL's mathematics functionality by including the `<glm/glm.hpp>` header:
+
+```cpp
+#include <glm/glm.hpp>
+```
+
+To extend the feature set supported by GLM and keeping the library as close to GLSL as possible, new features are implemented as extensions that can be included thought a separated header:
+
+```cpp
+// Include all GLM core / GLSL features
+#include <glm/glm.hpp> // vec2, vec3, mat4, radians
+
+// Include all GLM extensions
+#include <glm/ext.hpp> // perspective, translate, rotate
+
+glm::mat4 transform(glm::vec2 const& Orientation, glm::vec3 const& Translate, glm::vec3 const& Up)
+{
+    glm::mat4 Proj = glm::perspective(glm::radians(45.f), 1.33f, 0.1f, 10.f);
+    glm::mat4 ViewTranslate = glm::translate(glm::mat4(1.f), Translate);
+    glm::mat4 ViewRotateX = glm::rotate(ViewTranslate, Orientation.y, Up);
+    glm::mat4 View = glm::rotate(ViewRotateX, Orientation.x, Up);
+    glm::mat4 Model = glm::mat4(1.0f);
+    return Proj * View * Model;
+}
+```
+
+*Note: Including `<glm/glm.hpp>` and `<glm/ext.hpp>` is convenient but pull a lot of code which will significantly increase build time, particularly if these files are included in all source files. We may prefer to use the approaches describe in the two following sections to keep the project build fast.*
+
+### <a name="section1_2"></a> 1.2. Using separated headers
+
+GLM relies on C++ templates heavily, and may significantly increase compilation times for projects that use it. Hence, user projects could only include the features they actually use. Following is the list of all the core features, based on GLSL specification, headers:
+
+```cpp
+#include <glm/vec2.hpp>               // vec2, bvec2, dvec2, ivec2 and uvec2
+#include <glm/vec3.hpp>               // vec3, bvec3, dvec3, ivec3 and uvec3
+#include <glm/vec4.hpp>               // vec4, bvec4, dvec4, ivec4 and uvec4
+#include <glm/mat2x2.hpp>             // mat2, dmat2
+#include <glm/mat2x3.hpp>             // mat2x3, dmat2x3
+#include <glm/mat2x4.hpp>             // mat2x4, dmat2x4
+#include <glm/mat3x2.hpp>             // mat3x2, dmat3x2
+#include <glm/mat3x3.hpp>             // mat3, dmat3
+#include <glm/mat3x4.hpp>             // mat3x4, dmat2
+#include <glm/mat4x2.hpp>             // mat4x2, dmat4x2
+#include <glm/mat4x3.hpp>             // mat4x3, dmat4x3
+#include <glm/mat4x4.hpp>             // mat4, dmat4
+#include <glm/common.hpp>             // all the GLSL common functions: abs, min, mix, isnan, fma, etc.
+#include <glm/exponential.hpp>        // all the GLSL exponential functions: pow, log, exp2, sqrt, etc.
+#include <glm/geometric.hpp>          // all the GLSL geometry functions: dot, cross, reflect, etc.
+#include <glm/integer.hpp>            // all the GLSL integer functions: findMSB, bitfieldExtract, etc.
+#include <glm/matrix.hpp>             // all the GLSL matrix functions: transpose, inverse, etc.
+#include <glm/packing.hpp>            // all the GLSL packing functions: packUnorm4x8, unpackHalf2x16, etc.
+#include <glm/trigonometric.hpp>      // all the GLSL trigonometric functions: radians, cos, asin, etc.
+#include <glm/vector_relational.hpp>  // all the GLSL vector relational functions: equal, less, etc.
+```
+
+The following is a code sample using separated core headers and an extension:
+
+```cpp
+// Include GLM core features
+#include <glm/vec2.hpp>           // vec2
+#include <glm/vec3.hpp>           // vec3
+#include <glm/mat4x4.hpp>         // mat4
+#include <glm/trigonometric.hpp>  //radians
+
+// Include GLM extension
+#include <glm/ext/matrix_transform.hpp> // perspective, translate, rotate
+
+glm::mat4 transform(glm::vec2 const& Orientation, glm::vec3 const& Translate, glm::vec3 const& Up)
+{
+    glm::mat4 Proj = glm::perspective(glm::radians(45.f), 1.33f, 0.1f, 10.f);
+    glm::mat4 ViewTranslate = glm::translate(glm::mat4(1.f), Translate);
+    glm::mat4 ViewRotateX = glm::rotate(ViewTranslate, Orientation.y, Up);
+    glm::mat4 View = glm::rotate(ViewRotateX, Orientation.x, Up);
+    glm::mat4 Model = glm::mat4(1.0f);
+    return Proj * View * Model;
+}
+```
+
+### <a name="section1_3"></a> 1.3. Using extension headers
+
+Using GLM through split headers to minimize the project build time:
+
+```cpp
+// Include GLM vector extensions:
+#include <glm/ext/vector_float2.hpp>                // vec2
+#include <glm/ext/vector_float3.hpp>                // vec3
+#include <glm/ext/vector_trigonometric.hpp>         // radians
+
+// Include GLM matrix extensions:
+#include <glm/ext/matrix_float4x4.hpp>              // mat4
+#include <glm/ext/matrix_transform.hpp>             // perspective, translate, rotate
+
+glm::mat4 transform(glm::vec2 const& Orientation, glm::vec3 const& Translate, glm::vec3 const& Up)
+{
+    glm::mat4 Proj = glm::perspective(glm::radians(45.f), 1.33f, 0.1f, 10.f);
+    glm::mat4 ViewTranslate = glm::translate(glm::mat4(1.f), Translate);
+    glm::mat4 ViewRotateX = glm::rotate(ViewTranslate, Orientation.y, Up);
+    glm::mat4 View = glm::rotate(ViewRotateX, Orientation.x, Up);
+    glm::mat4 Model = glm::mat4(1.0f);
+    return Proj * View * Model;
+}
+```
+
+### <a name="section1_4"></a> 1.4. Dependencies
+
+GLM does not depend on external libraries or headers such as `<GL/gl.h>`, [`<GL/glcorearb.h>`](http://www.opengl.org/registry/api/GL/glcorearb.h), `<GLES3/gl3.h>`, `<GL/glu.h>`, or `<windows.h>`.
+
+### <a name="section1_5"></a> 1.5. Finding GLM with CMake
+
+When installed, GLM provides the CMake package configuration files `glmConfig.cmake` and `glmConfigVersion.cmake`.
+
+To use these configurations files, you may need to set the `glm_DIR` variable to the directory containing the configuration files `<installation prefix>/lib/cmake/glm/`.
+
+Use the `find_package` CMake command to load the configurations into your project. Lastly, either link your executable against the `glm::glm` target or add `${GLM_INCLUDE_DIRS}` to your target's include directories:
+
+```cmake
+set(glm_DIR <installation prefix>/lib/cmake/glm) # if necessary
+find_package(glm REQUIRED)
+target_link_libraries(<your executable> glm::glm)

+
+To use GLM as a submodule in a project instead, use `add_subdirectory` to expose the same target, or add the directory to your target's

+## <a name="section2"></a> 2. Preprocessor configurations
+
+### <a name="section2_1"></a> 2.1. GLM\_FORCE\_MESSAGES: Platform auto detection and default configuration
+
+When included, GLM will first automatically detect the compiler used, the C++ standard supported, the compiler arguments used to configure itself matching the build environment.
+
+For example, if the compiler arguments request AVX code generation, GLM will rely on its code path providing AVX optimizations when available.
+
+We can change GLM configuration using specific C++ preprocessor defines that must be declared before including any GLM headers.
+
+Using `GLM_FORCE_MESSAGES`, GLM will report the configuration as part of the build log.
+
+```cpp
+#define GLM_FORCE_MESSAGES // Or defined when building (e.g. -DGLM_FORCE_SWIZZLE)
+#include <glm/glm.hpp>
+```
+
+Example of configuration log generated by `GLM_FORCE_MESSAGES`:
+
+```plaintext
+GLM: version 0.9.9.1
+GLM: C++ 17 with extensions
+GLM: Clang compiler detected
+GLM: x86 64 bits with AVX instruction set build target
+GLM: Linux platform detected
+GLM: GLM_FORCE_SWIZZLE is undefined. swizzling functions or operators are disabled.
+GLM: GLM_FORCE_SIZE_T_LENGTH is undefined. .length() returns a glm::length_t, a typedef of int following GLSL.
+GLM: GLM_FORCE_UNRESTRICTED_GENTYPE is undefined. Follows strictly GLSL on valid function genTypes.
+GLM: GLM_FORCE_DEPTH_ZERO_TO_ONE is undefined. Using negative one to one depth clip space.
+GLM: GLM_FORCE_LEFT_HANDED is undefined. Using right handed coordinate system.
+```
+
+The following subsections describe each configurations and defines.
+
+### <a name="section2_2"></a> 2.2. GLM\_FORCE\_PLATFORM\_UNKNOWN: Force GLM to no detect the build platform
+
+`GLM_FORCE_PLATFORM_UNKNOWN` prevents GLM from detecting the build platform.
+
+### <a name="section2_3"></a> 2.3. GLM\_FORCE\_COMPILER\_UNKNOWN: Force GLM to no detect the C++ compiler
+
+`GLM_FORCE_COMPILER_UNKNOWN` prevents GLM from detecting the C++ compiler.
+
+### <a name="section2_4"></a> 2.4. GLM\_FORCE\_ARCH\_UNKNOWN: Force GLM to no detect the build architecture
+
+`GLM_FORCE_ARCH_UNKNOWN` prevents GLM from detecting the build target architecture.
+
+### <a name="section2_5"></a> 2.5. GLM\_FORCE\_CXX\_UNKNOWN: Force GLM to no detect the C++ standard
+
+`GLM_FORCE_CSS_UNKNOWN` prevents GLM from detecting the C++ compiler standard support.
+
+### <a name="section2_6"></a> 2.6. GLM\_FORCE\_CXX**: C++ language detection
+
+GLM will automatically take advantage of compilers’ language extensions when enabled. To increase cross platform compatibility and to avoid compiler extensions, a programmer can define `GLM_FORCE_CXX98` before
+any inclusion of `<glm/glm.hpp>` to restrict the language feature set C++98:
+
+```cpp
+#define GLM_FORCE_CXX98
+#include <glm/glm.hpp>
+```
+
+For C++11, C++14, and C++17 equivalent defines are available:
+
+* `GLM_FORCE_CXX11`
+* `GLM_FORCE_CXX14`
+* `GLM_FORCE_CXX17`
+
+```cpp
+#define GLM_FORCE_CXX11
+#include <glm/glm.hpp>
+
+// If the compiler doesn’t support C++11, compiler errors will happen.
+```
+
+`GLM_FORCE_CXX17` overrides `GLM_FORCE_CXX14`; `GLM_FORCE_CXX14` overrides `GLM_FORCE_CXX11`; and `GLM_FORCE_CXX11` overrides `GLM_FORCE_CXX98` defines.
+
+### <a name="section2_7"></a> 2.7. GLM\_FORCE\_EXPLICIT\_CTOR: Requiring explicit conversions
+
+GLSL supports implicit conversions of vector and matrix types. For example, an ivec4 can be implicitly converted into `vec4`.
+
+Often, this behaviour is not desirable but following the spirit of the library, this is the default behavior in GLM. However, GLM 0.9.6 introduced the define `GLM_FORCE_EXPLICIT_CTOR` to require explicit conversion for GLM types.
+
+```cpp
+#include <glm/glm.hpp>
+
+void foo()
+{
+    glm::ivec4 a;
+    ...
+
+    glm::vec4 b(a); // Explicit conversion, OK
+    glm::vec4 c = a; // Implicit conversion, OK
+    ...
+}
+```
+
+With `GLM_FORCE_EXPLICIT_CTOR` define, implicit conversions are not allowed:
+
+```cpp
+#define GLM_FORCE_EXPLICIT_CTOR
+#include <glm/glm.hpp>
+
+void foo()
+{
+    glm::ivec4 a;
+    {
+        glm::vec4 b(a); // Explicit conversion, OK
+        glm::vec4 c = a; // Implicit conversion, ERROR
+        ...
+}
+```
+
+### <a name="section2_8"></a> 2.8. GLM\_FORCE\_INLINE: Force inline
+
+To push further the software performance, a programmer can define `GLM_FORCE_INLINE` before any inclusion of `<glm/glm.hpp>` to force the compiler to inline GLM code.
+
+```cpp
+#define GLM_FORCE_INLINE
+#include <glm/glm.hpp>
+```
+
+### <a name="section2_9"></a> 2.9. GLM\_FORCE\_ALIGNED\_GENTYPES: Force GLM to enable aligned types
+
+Every object type has the property called alignment requirement, which is an integer value (of type `std::size_t`, always a power of 2) representing the number of bytes between successive addresses at which objects of this type can be allocated. The alignment requirement of a type can be queried with alignof or `std::alignment_of`. The pointer alignment function `std::align` can be used to obtain a suitably-aligned pointer within some buffer, and `std::aligned_storage` can be used to obtain suitably-aligned storage.
+
+Each object type imposes its alignment requirement on every object of that type; stricter alignment (with larger alignment requirement) can be requested using C++11 `alignas`.
+
+In order to satisfy alignment requirements of all non-static members of a class, padding may be inserted after some of its members.
+
+GLM supports both packed and aligned types. Packed types allow filling data structure without inserting extra padding. Aligned GLM types align addresses based on the size of the value type of a GLM type.
+
+```cpp
+#define GLM_FORCE_ALIGNED_GENTYPES
+#include <glm/glm.hpp>
+#include <glm/gtc/type_aligned.hpp>
+
+typedef glm::aligned_vec4 vec4a;
+typedef glm::packed_vec4 vec4p;
+```
+
+### <a name="section2_10"></a> 2.10. GLM\_FORCE\_DEFAULT\_ALIGNED\_GENTYPES: Force GLM to use aligned types by default
+
+GLM allows using aligned types by default for vector types using `GLM_FORCE_DEFAULT_ALIGNED_GENTYPES`:
+
+```cpp
+#define GLM_FORCE_DEFAULT_ALIGNED_GENTYPES
+#include <glm/glm.hpp>
+
+struct MyStruct
+{
+    glm::vec4 a;
+    float b;
+    glm::vec3 c;
+};
+
+void foo()
+{
+    printf("MyStruct requires memory padding: %d bytes\n", sizeof(MyStruct));
+}
+
+>>> MyStruct requires memory padding: 48 bytes
+```
+
+```cpp
+#include <glm/glm.hpp>
+
+struct MyStruct
+{
+    glm::vec4 a;
+    float b;
+    glm::vec3 c;
+};
+
+void foo()
+{
+    printf("MyStruct is tightly packed: %d bytes\n", sizeof(MyStruct));
+}
+
+>>> MyStruct is tightly packed: 32 bytes
+```
+
+*Note: GLM SIMD optimizations require the use of aligned types*
+
+### <a name="section2_11"></a> 2.11. GLM\_FORCE\_INTRINSICS: Using SIMD optimizations
+
+GLM provides some SIMD optimizations based on [compiler intrinsics](https://msdn.microsoft.com/en-us/library/26td21ds.aspx).
+These optimizations will be automatically thanks to compiler arguments when `GLM_FORCE_INTRINSICS` is defined before including GLM files.
+For example, if a program is compiled with Visual Studio using `/arch:AVX`, GLM will detect this argument and generate code using AVX instructions automatically when available.
+
+It’s possible to avoid the instruction set detection by forcing the use of a specific instruction set with one of the fallowing define:
+`GLM_FORCE_SSE2`, `GLM_FORCE_SSE3`, `GLM_FORCE_SSSE3`, `GLM_FORCE_SSE41`, `GLM_FORCE_SSE42`, `GLM_FORCE_AVX`, `GLM_FORCE_AVX2` or `GLM_FORCE_AVX512`.
+
+The use of intrinsic functions by GLM implementation can be avoided using the define `GLM_FORCE_PURE` before any inclusion of GLM headers. This can be particularly useful if we want to rely on C++14 `constexpr`.
+
+```cpp
+#define GLM_FORCE_PURE
+#include <glm/glm.hpp>
+
+static_assert(glm::vec4::length() == 4, "Using GLM C++ 14 constexpr support for compile time tests");
+
+// GLM code will be compiled using pure C++ code without any intrinsics
+```
+
+```cpp
+#define GLM_FORCE_SIMD_AVX2
+#include <glm/glm.hpp>
+
+// If the compiler doesn’t support AVX2 instrinsics, compiler errors will happen.
+```
+
+Additionally, GLM provides a low level SIMD API in glm/simd directory for users who are really interested in writing fast algorithms.
+
+### <a name="section2_12"></a> 2.12. GLM\_FORCE\_PRECISION\_**: Default precision
+
+C++ does not provide a way to implement GLSL default precision selection (as defined in GLSL 4.10 specification section 4.5.3) with GLSL-like syntax.
+
+```glsl
+precision mediump int;
+precision highp float;
+```
+
+To use the default precision functionality, GLM provides some defines that need to added before any include of `glm.hpp`:
+
+```cpp
+#define GLM_FORCE_PRECISION_MEDIUMP_INT
+#define GLM_FORCE_PRECISION_HIGHP_FLOAT
+#include <glm/glm.hpp>
+```
+
+Available defines for floating point types (`glm::vec\*`, `glm::mat\*`):
+
+* `GLM_FORCE_PRECISION_LOWP_FLOAT`: Low precision
+* `GLM_FORCE_PRECISION_MEDIUMP_FLOAT`: Medium precision
+* `GLM_FORCE_PRECISION_HIGHP_FLOAT`: High precision (default)
+
+Available defines for floating point types (`glm::dvec\*`, `glm::dmat\*`):
+
+* `GLM_FORCE_PRECISION_LOWP_DOUBLE`: Low precision
+* `GLM_FORCE_PRECISION_MEDIUMP_DOUBLE`: Medium precision
+* `GLM_FORCE_PRECISION_HIGHP_DOUBLE`: High precision (default)
+
+Available defines for signed integer types (`glm::ivec\*`):
+
+* `GLM_FORCE_PRECISION_LOWP_INT`: Low precision
+* `GLM_FORCE_PRECISION_MEDIUMP_INT`: Medium precision
+* `GLM_FORCE_PRECISION_HIGHP_INT`: High precision (default)
+
+Available defines for unsigned integer types (`glm::uvec\*`):
+
+* `GLM_FORCE_PRECISION_LOWP_UINT`: Low precision
+* `GLM_FORCE_PRECISION_MEDIUMP_UINT`: Medium precision
+* `GLM_FORCE_PRECISION_HIGHP_UINT`: High precision (default)
+
+### <a name="section2_13"></a> 2.13. GLM\_FORCE\_SINGLE\_ONLY: Removed explicit 64-bits floating point types
+
+Some platforms (Dreamcast) doesn't support double precision floating point values. To compile on such platforms, GCC has the `--m4-single-only` build argument. When defining `GLM_FORCE_SINGLE_ONLY` before including GLM headers, GLM releases the requirement of double precision floating point values support. Effectivement, all the float64 types are no longer defined and double behaves like float.
+
+### <a name="section2_14"></a> 2.14. GLM\_FORCE\_SWIZZLE: Enable swizzle operators
+
+Shader languages like GLSL often feature so-called swizzle expressions, which may be used to freely select and arrange a vector's components. For example, `variable.x`, `variable.xzy` and `variable.zxyy` respectively form a scalar, a 3D vector and a 4D vector.  The result of a swizzle expression in GLSL can be either an R-value or an L-value. Swizzle expressions can be written with characters from exactly one of `xyzw` (usually for positions), `rgba` (usually for colors), and `stpq` (usually for texture coordinates).
+
+```glsl
+vec4 A;
+vec2 B;
+
+B.yx = A.wy;
+B = A.xx;
+vec3 C = A.bgr;
+vec3 D = B.rsz; // Invalid, won't compile
+```
+
+GLM supports some of this functionality. Swizzling can be enabled by defining `GLM_FORCE_SWIZZLE`.
+
+*Note: Enabling swizzle expressions will massively increase the size of your binaries and the time it takes to compile them!*
+
+GLM has two levels of swizzling support described in the following subsections.
+
+#### 2.14.1. Swizzle functions for standard C++ 98
+
+When compiling GLM as C++98, R-value swizzle expressions are simulated through member functions of each vector type.
+
+```cpp
+#define GLM_FORCE_SWIZZLE // Or defined when building (e.g. -DGLM_FORCE_SWIZZLE)
+#include <glm/glm.hpp>
+
+void foo()
+{
+    glm::vec4 const ColorRGBA = glm::vec4(1.0f, 0.5f, 0.0f, 1.0f);
+    glm::vec3 const ColorBGR = ColorRGBA.bgr();
+
+    glm::vec3 const PositionA = glm::vec3(1.0f, 0.5f, 0.0f);
+    glm::vec3 const PositionB = PositionXYZ.xyz() * 2.0f;
+
+    glm::vec2 const TexcoordST = glm::vec2(1.0f, 0.5f);
+    glm::vec4 const TexcoordSTPQ = TexcoordST.stst();
+}
+```
+
+Swizzle operators return a **copy** of the component values, and thus *can't* be used as L-values to change a vector's values.
+
+```cpp
+#define GLM_FORCE_SWIZZLE
+#include <glm/glm.hpp>
+
+void foo()
+{
+  glm::vec3 const A = glm::vec3(1.0f, 0.5f, 0.0f);
+
+  // No compiler error, but A is not modified.
+  // An anonymous copy is being modified (and then discarded).
+  A.bgr() = glm::vec3(2.0f, 1.5f, 1.0f); // A is not modified!
+}
+```
+
+#### 2.14.2. Swizzle operations for C++ 98 with language extensions
+
+Visual C++, GCC and Clang support, as a _non-standard language extension_, anonymous `struct`s as `union` members. This permits a powerful swizzling implementation that both allows L-value swizzle expressions and GLSL-like syntax. To use this feature, the language extension must be enabled by a supporting compiler and `GLM_FORCE_SWIZZLE` must be `#define`d.
+
+```cpp
+#define GLM_FORCE_SWIZZLE
+#include <glm/glm.hpp>
+
+// Only guaranteed to work with Visual C++!
+// Some compilers that support Microsoft extensions may compile this.
+void foo()
+{
+  glm::vec4 ColorRGBA = glm::vec4(1.0f, 0.5f, 0.0f, 1.0f);
+
+  // l-value:
+  glm::vec4 ColorBGRA = ColorRGBA.bgra;
+
+  // r-value:
+  ColorRGBA.bgra = ColorRGBA;
+
+  // Both l-value and r-value
+  ColorRGBA.bgra = ColorRGBA.rgba;
+}
+```
+
+This version returns implementation-specific objects that _implicitly convert_ to their respective vector types.  As a consequence of this design, these extra types **can't be directly used** as C++ function arguments; they must be converted through constructors or `operator()`.
+
+```cpp
+#define GLM_FORCE_SWIZZLE
+#include <glm/glm.hpp>
+
+using namespace glm;
+
+void foo()
+{
+  vec4 Color = vec4(1.0f, 0.5f, 0.0f, 1.0f);
+
+  // Generates compiler errors. Color.rgba is not a vector type.
+  vec4 ClampedA = clamp(Color.rgba, 0.f, 1.f); // ERROR
+
+  // Explicit conversion through a constructor
+  vec4 ClampedB = clamp(vec4(Color.rgba), 0.f, 1.f); // OK
+
+  // Explicit conversion through operator()
+  vec4 ClampedC = clamp(Color.rgba(), 0.f, 1.f); // OK
+}
+```
+
+*Note: The implementation has a caveat: Swizzle operator types must be different on both size of the equal operator or the operation will fail. There is no known fix for this issue to date*
+
+### <a name="section2_15"></a> 2.15. GLM\_FORCE\_XYZW\_ONLY: Only exposes x, y, z and w components
+
+Following GLSL specifications, GLM supports three sets of components to access vector types member: x, y, z, w; r, g, b, a; and s, t, p, q.
+Also, this is making vector component very expressive in the code, it may make debugging vector types a little cubersom as the debuggers will typically display three time the values for each compoenents due to the existence of the three sets.
+
+To simplify vector types, GLM allows exposing only x, y, z and w components thanks to `GLM_FORCE_XYZW_ONLY` define.
+
+### <a name="section2_16"></a> 2.16. GLM\_FORCE\_LEFT\_HANDED: Force left handed coordinate system
+
+By default, OpenGL is using a right handed coordinate system. However, others APIs such as Direct3D have done different choice and relies on the left handed coordinate system.
+
+GLM allows switching the coordinate system to left handed by defining `GLM_FORCE_LEFT_HANDED`.
+
+### <a name="section2_17"></a> 2.17. GLM\_FORCE\_DEPTH\_ZERO\_TO\_ONE: Force the use of a clip space between 0 to 1
+
+By default, OpenGL is using a -1 to 1 clip space in Z-axis. However, others APIs such as Direct3D relies on a clip space between 0 to 1 in Z-axis.
+
+GLM allows switching the clip space in Z-axis to 0 to 1 by defining `GLM_FORCE_DEPTH_ZERO_TO_ONE`.
+
+### <a name="section2_18"></a> 2.18. GLM\_FORCE\_SIZE\_T\_LENGTH: Vector and matrix static size
+
+GLSL supports the member function .length() for all vector and matrix types.
+
+```cpp
+#include <glm/glm.hpp>
+
+void foo(vec4 const& v)
+{
+    int Length = v.length();
+    ...
+}
+```
+
+This function returns an `int` however this function typically interacts with STL `size_t` based code. GLM provides `GLM_FORCE_SIZE_T_LENGTH` pre-processor configuration so that member functions `length()` return a `size_t`.
+
+Additionally, GLM defines the type `glm::length_t` to identify `length()` returned type, independently from `GLM_FORCE_SIZE_T_LENGTH`.
+
+```cpp
+#define GLM_FORCE_SIZE_T_LENGTH
+#include <glm/glm.hpp>
+
+void foo(vec4 const& v)
+{
+    glm::length_t Length = v.length();
+    ...
+}
+```
+
+### <a name="section2_19"></a> 2.19. GLM\_FORCE\_UNRESTRICTED\_GENTYPE: Removing genType restriction
+
+GLSL has restrictions on types supported by certain functions that may appear excessive.
+By default, GLM follows the GLSL specification as accurately as possible however it's possible to relax these rules using `GLM_FORCE_UNRESTRICTED_GENTYPE` define.
+
+```cpp
+#include <glm/glm.hpp>
+
+float average(float const A, float const B)
+{
+    return glm::mix(A, B, 0.5f); // By default glm::mix only supports floating-point types
+}
+```
+
+By defining GLM\_FORCE\_UNRESTRICTED\_GENTYPE, we allow using integer types:
+
+```cpp
+#define GLM_FORCE_UNRESTRICTED_GENTYPE
+#include <glm/glm.hpp>
+
+int average(int const A, int const B)
+{
+    return glm::mix(A, B, 0.5f); // integers are ok thanks to GLM_FORCE_UNRESTRICTED_GENTYPE
+}
+```
+
+### <a name="section2_20"></a> 2.20. GLM\_FORCE\_SILENT\_WARNINGS: Silent C++ warnings from language extensions
+
+When using /W4 on Visual C++ or -Wpedantic on GCC, for example, the compilers will generate warnings for using C++ language extensions (/Za with Visual C++) such as anonymous struct.
+GLM relies on anonymous structs for swizzle operators and aligned vector types. To silent those warnings define `GLM_FORCE_SILENT_WARNINGS` before including GLM headers.
+
+### <a name="section2_21"></a> 2.21. GLM\_FORCE\_QUAT\_DATA\_WXYZ: Force GLM to store quat data as w,x,y,z instead of x,y,z,w
+
+By default GLM store quaternion components with the x, y, z, w order. `GLM_FORCE_QUAT_DATA_WXYZ` allows switching the quaternion data storage to the w, x, y, z order.

+
+Vector and matrix types with defined precisions, e.g. `i8vec4`, which is a 4D vector of signed 8-bit integers.
+
+`<glm/gtc/type\_precision.hpp>` need to be included to use the features of this extension.
+
+### <a name="section4_18"></a> 4.18. GLM\_GTC\_type\_ptr
+
+Facilitate interactions between pointers to basic types (e.g. `float*`) and GLM types (e.g. `mat4`).
+
+This extension defines an overloaded function, `glm::value_ptr`, which returns a pointer to the memory layout of any GLM vector or matrix (`vec3`, `mat4`, etc.). Matrix types store their values in column-major order. This is useful for uploading data to matrices or for copying data to buffer objects.
+
+```cpp
+// GLM_GTC_type_ptr provides a safe solution:
+#include <glm/glm.hpp>
+#include <glm/gtc/type_ptr.hpp>
+
+void foo()
+{
+    glm::vec4 v(0.0f);
+    glm::mat4 m(1.0f);
+    ...
+    glVertex3fv(glm::value_ptr(v))
+    glLoadMatrixfv(glm::value_ptr(m));
+}
+
+// Another solution, this one inspired by the STL:
+#include <glm/glm.hpp>
+
+void foo()
+{
+    glm::vec4 v(0.0f);
+    glm::mat4 m(1.0f);
+    ...
+    glVertex3fv(&v[0]);
+    glLoadMatrixfv(&m[0][0]);
+}
+```
+
+*Note: It would be possible to implement [`glVertex3fv`](http://www.opengl.org/sdk/docs/man2/xhtml/glVertex.xml)(glm::vec3(0)) in C++ with the appropriate cast operator that would result as an
+implicit cast in this example. However cast operators may produce programs running with unexpected behaviours without build error or any form of notification.*

+## <a name="section6"></a> 6. Known issues
+
+This section reports GLSL features that GLM can't accurately emulate due to language restrictions.
+
+### <a name="section6_1"></a> 6.1. not function
+
+The GLSL function 'not' is a keyword in C++. To prevent name collisions and ensure a consistent API, the name `not\_` (note the underscore) is used instead.
+
+### <a name="section6_2"></a> 6.2. Precision qualifiers support
+
+GLM supports GLSL precision qualifiers through prefixes instead of qualifiers. For example, GLM exposes \verb|lowp_vec4|, \verb|mediump_vec4| and \verb|highp_vec4| as variations of \verb|vec4|.
+
+Similarly to GLSL, GLM precision qualifiers are used to trade precision of operations in term of [ULPs](http://en.wikipedia.org/wiki/Unit_in_the_last_place) for better performance. By default, all the types use high precision.
+
+```cpp
+// Using precision qualifier in GLSL:
+
+ivec3 foo(in vec4 v)
+{
+    highp vec4 a = v;
+    mediump vec4 b = a;
+    lowp ivec3 c = ivec3(b);
+    return c;
+}
+
+// Using precision qualifier in GLM:
+
+#include <glm/glm.hpp>
+
+ivec3 foo(const vec4 & v)
+{
+    highp_vec4 a = v;
+    medium_vec4 b = a;
+    lowp_ivec3 c = glm::ivec3(b);
+    return c;
+}

+
+## <a name="section7"></a> 7. FAQ
+
+### <a name="section7_1"></a> 7.1 Why GLM follows GLSL specification and conventions?
+
+Following GLSL conventions is a really strict policy of GLM. It has been designed following the idea that everyone does its own math library with his own conventions. The idea is that brilliant developers (the OpenGL ARB) worked together and agreed to make GLSL. Following GLSL conventions
+is a way to find consensus. Moreover, basically when a developer knows GLSL, he knows GLM.
+
+### <a name="section7_2"></a> 7.2. Does GLM run GLSL program?
+
+No, GLM is a C++ implementation of a subset of GLSL.
+
+### <a name="section7_3"></a> 7.3. Does a GLSL compiler build GLM codes?
+
+No, this is not what GLM attends to do.
+
+### <a name="section7_4"></a> 7.4. Should I use ‘GTX’ extensions?
+
+GTX extensions are qualified to be experimental extensions. In GLM this means that these extensions might change from version to version without any restriction. In practice, it doesn’t really change except time to
+time. GTC extensions are stabled, tested and perfectly reliable in time. Many GTX extensions extend GTC extensions and provide a way to explore features and implementations and APIs and then are promoted to GTC
+extensions. This is fairly the way OpenGL features are developed; through extensions.
+
+Stating with GLM 0.9.9, to use experimental extensions, an application must define GLM_ENABLE_EXPERIMENTAL.
+
+### <a name="section7_5"></a> 7.5. Where can I ask my questions?
+
+A good place is [stackoverflow](http://stackoverflow.com/search?q=GLM) using the GLM tag.
+
+### <a name="section7_6"></a> 7.6. Where can I find the documentation of extensions?
+
+The Doxygen generated documentation includes a complete list of all extensions available. Explore this [*API documentation*](http://glm.g-truc.net/html/index.html) to get a complete
+view of all GLM capabilities!
+
+### <a name="section7_7"></a> 7.7. Should I use ‘using namespace glm;’?
+
+NO! Chances are that if using namespace glm; is called, especially in a header file, name collisions will happen as GLM is based on GLSL which uses common tokens for types and functions. Avoiding using namespace
+glm; will a higher compatibility with third party library and SDKs.
+
+### <a name="section7_8"></a> 7.8. Is GLM fast?
+
+GLM is mainly designed to be convenient and that's why it is written against the GLSL specification.
+
+Following the Pareto principle where 20% of the code consumes 80% of the execution time, GLM operates perfectly on the 80% of the code that consumes 20% of the performances. Furthermore, thanks to the lowp,
+mediump and highp qualifiers, GLM provides approximations which trade precision for performance. Finally, GLM can automatically produce SIMD optimized code for functions of its implementation.
+
+However, on performance critical code paths, we should expect that dedicated algorithms should be written to reach peak performance.
+
+### <a name="section7_9"></a> 7.9. When I build with Visual C++ with /W4 warning level, I have warnings...
+
+You should not have any warnings even in `/W4` mode. However, if you expect such level for your code, then you should ask for the same level to the compiler by at least disabling the Visual C++ language extensions
+(`/Za`) which generates warnings when used. If these extensions are enabled, then GLM will take advantage of them and the compiler will generate warnings.
+
+### <a name="section7_10"></a> 7.10. Why some GLM functions can crash because of division by zero?
+
+GLM functions crashing is the result of a domain error. Such behavior follows the precedent set by C and C++'s standard library. For example, it’s a domain error to pass a null vector (all zeroes) to glm::normalize function, or to pass a negative number into std::sqrt.
+
+### <a name="section7_11"></a> 7.11. What unit for angles is used in GLM?
+
+GLSL is using radians but GLU is using degrees to express angles. This has caused GLM to use inconsistent units for angles. Starting with GLM 0.9.6, all GLM functions are using radians. For more information, follow
+the [link](http://www.g-truc.net/post-0693.html#menu).
+
+### <a name="section7_12"></a> 7.12. Windows headers cause build errors...
+
+Some Windows headers define min and max as macros which may cause compatibility with third party libraries such as GLM.
+It is highly recommended to [`define NOMINMAX`](http://stackoverflow.com/questions/4913922/possible-problems-with-nominmax-on-visual-c) before including Windows headers to workaround this issue.
+To workaround the incompatibility with these macros, GLM will systematically undef these macros if they are defined.
+
+### <a name="section7_13"></a> 7.13. Constant expressions support
+
+GLM has some C++ [constant expressions](http://en.cppreference.com/w/cpp/language/constexpr) support. However, GLM automatically detects the use of SIMD instruction sets through compiler arguments to populate its implementation with SIMD intrinsics.
+Unfortunately, GCC and Clang doesn't support SIMD instrinsics as constant expressions. To allow constant expressions on all vectors and matrices types, define `GLM_FORCE_PURE` before including GLM headers.

+
+### <a name="section9_1"></a> 9.1. Submitting bug reports
+
+Bug should be reported on Github using the [issue page](https://github.com/g-truc/glm/issues).
+
+A minimal code to reproduce the issue will help.
+
+Additional, bugs can be configuration specific. We can report the configuration by defining `GLM_FORCE_MESSAGES` before including GLM headers then build and copy paste the build messages GLM will output.
+
+```cpp
+#define GLM_FORCE_MESSAGES
+#include <glm/glm.hpp>
+```
+
+An example of build messages generated by GLM:
+
+```plaintext
+GLM: 0.9.9.1
+GLM: C++ 17 with extensions
+GLM: GCC compiler detected"
+GLM: x86 64 bits with AVX instruction set build target
+GLM: Linux platform detected
+GLM: GLM_FORCE_SWIZZLE is undefined. swizzling functions or operators are disabled.
+GLM: GLM_FORCE_SIZE_T_LENGTH is undefined. .length() returns a glm::length_t, a typedef of int following GLSL.
+GLM: GLM_FORCE_UNRESTRICTED_GENTYPE is undefined. Follows strictly GLSL on valid function genTypes.
+GLM: GLM_FORCE_DEPTH_ZERO_TO_ONE is undefined. Using negative one to one depth clip space.
+GLM: GLM_FORCE_LEFT_HANDED is undefined. Using right handed coordinate system.
+```
+
+### <a name="section9_2"></a> 9.2. Contributing to GLM with pull request
+
+This tutorial will show us how to successfully contribute a bug-fix to GLM using GitHub's Pull Request workflow.
+
+We will be typing git commands in the Terminal. Mac and Linux users may have git pre-installed. You can download git from [here](http://git-scm.com/downloads).
+
+The tutorial assumes you have some basic understanding of git concepts - repositories, branches, commits, etc. Explaining it all from scratch is beyond the scope of this tutorial. Some good links to learn git basics are: [Link 1](http://git-scm.com/book/en/Getting-Started-Git-Basics), [Link 2](https://www.atlassian.com/git/tutorial/git-basics)
+
+#### Step 1: Setup our GLM Fork
+
+We will make our changes in our own copy of the GLM sitory. On the GLM GitHub repo and we press the Fork button.
+We need to download a copy of our fork to our local machine. In the terminal, type:
+
+```plaintext
+>>> git clone <our-repository-fork-git-url>
+```
+
+This will clone our fork repository into the current folder.
+
+We can find our repository git url on the Github reposotory page. The url looks like this: `https://github.com/<our-username>/<repository-name>.git`
+
+#### Step 2: Synchronizing our fork
+
+We can use the following command to add `upstream` (original project repository) as a remote repository so that we can fetch the latest GLM commits into our branch and keep our forked copy is synchronized.
+
+```plaintext
+>>> git remote add upstream https://github.com/processing/processing.git
+```
+
+To synchronize our fork to the latest commit in the GLM repository, we can use the following command:
+
+```plaintext
+>>> git fetch upstream
+```
+
+Then, we can merge the remote master branch to our current branch:
+
+```plaintext
+>>> git merge upstream/master
+```
+
+Now our local copy of our fork has been synchronized. However, the fork's copy is not updated on GitHub's servers yet. To do that, use:
+
+```plaintext
+>>> git push origin master
+```
+
+#### Step 3: Modifying our GLM Fork
+
+Our fork is now setup and we are ready to modify GLM to fix a bug.
+
+It's a good practice to make changes in our fork in a separate branch than the master branch because we can submit only one pull request per branch.
+
+Before creating a new branch, it's best to synchronize our fork and then create a new branch from the latest master branch.
+
+If we are not on the master branch, we should switch to it using:
+
+```plaintext
+>>> git checkout master
+```
+
+To create a new branch called `bugifx`, we use:
+
+```plaintext
+git branch bugfix
+```
+
+Once the code changes for the fix is done, we need to commit the changes:
+
+```plaintext
+>>> git commit -m "Resolve the issue that caused problem with a specific fix #432"
+```
+
+The commit message should be as specific as possible and finished by the bug number in the [GLM GitHub issue page](https://github.com/g-truc/glm/issues)
+
+Finally, we need to push our changes in our branch to our GitHub fork using:
+
+```plaintext
+>>> git push origin bugfix
+```
+
+Some things to keep in mind for a pull request:
+
+* Keep it minimal: Try to make the minimum required changes to fix the issue. If we have added any debugging code, we should remove it.
+* A fix at a time: The pull request should deal with one issue at a time only, unless two issue are so interlinked they must be fixed together.
+* Write a test: GLM is largely unit tests. Unit tests are in `glm/test` directory. We should also add tests for the fixes we provide to ensure future regression doesn't happen.
+* No whitespace changes: Avoid unnecessary formatting or whitespace changes in other parts of the code. Be careful with auto-format options in the code editor which can cause wide scale formatting changes.
+* Follow [GLM Code Style](#section9_3) for consistency.
+* Tests passes: Make sure GLM build and tests don't fail because of the changes.
+
+#### Step 4: Submitting a Pull Request
+
+We need to submit a pull request from the `bugfix` branch to GLM's master branch.
+
+On the fork github page, we can click on the *Pull Request* button. Then we can describe our pull request. Finally we press *Send Pull Request*.
+
+Please be patient and give them some time to go through it.
+
+The pull request review may suggest additional changes. So we can make those changes in our branch, and push those changes to our fork repository. Our pull request will always include the latest changes in our branch on GitHub, so we don't need to resubmit the pull request.
+
+Once your changes have been accepted, a project maintainer will merge our pull request.
+
+We are grateful to the users for their time and effort in contributing fixes.
+
+### <a name="section9_3"></a> 9.3. Coding style
+
+#### Indentation
+
+Always tabs. Never spaces.
+
+#### Spacing
+
+No space after if. Use if(blah) not if (blah). Example if/else block:
+
+```cpp
+if(blah)
+{
+    // yes like this
+}
+else
+{
+    // something besides
+}
+```
+
+Single line if blocks:
+
+```cpp
+if(blah)
+    // yes like this
+else
+    // something besides
+```
+
+No spaces inside parens:
+
+```cpp
+if (blah)    // No
+if( blah )   // No
+if ( blah )  // No
+if(blah)     // Yes
+```
+
+Use spaces before/after commas:
+
+```cpp
+someFunction(apple,bear,cat);     // No
+someFunction(apple, bear, cat);   // Yes
+```
+
+Use spaces before/after use of `+, -, *, /, %, >>, <<, |, &, ^, ||, &&` operators:
+
+```cpp
+vec4 v = a + b;
+```
+
+#### Blank lines
+
+One blank line after the function blocks.
+
+#### Comments
+
+Always one space after the // in single line comments
+
+One space before // at the end of a line (that has code as well)
+
+Try to use // comments inside functions, to make it easier to remove a whole block via /\* \*/
+
+#### Cases
+
+```cpp
+#define GLM_MY_DEFINE 76
+
+class myClass
+{};
+
+myClass const MyClass;
+
+namespace glm{ // glm namespace is for public code
+namespace detail // glm::detail namespace is for implementation detail
+{
+    float myFunction(vec2 const& V)
+    {
+        return V.x + V.y;
+    }
+
+    float myFunction(vec2 const* const V)
+    {
+        return V->x + V->y;
+    }
+}//namespace detail
+}//namespace glm

+![glm](/doc/manual/logo-mini.png)
+
+[OpenGL Mathematics](http://glm.g-truc.net/) (*GLM*) is a header only C++ mathematics library for graphics software based on the [OpenGL Shading Language (GLSL) specifications](https://www.opengl.org/registry/doc/GLSLangSpec.4.50.diff.pdf).
+
+*GLM* provides classes and functions designed and implemented with the same naming conventions and functionality than *GLSL* so that anyone who knows *GLSL*, can use *GLM* as well in C++.
+
+This project isn't limited to *GLSL* features. An extension system, based on the *GLSL* extension conventions, provides extended capabilities: matrix transformations, quaternions, data packing, random numbers, noise, etc...
+
+This library works perfectly with *[OpenGL](https://www.opengl.org)* but it also ensures interoperability with other third party libraries and SDK. It is a good candidate for software rendering (raytracing / rasterisation), image processing, physics simulations and any development context that requires a simple and convenient mathematics library.
+
+*GLM* is written in C++98 but can take advantage of C++11 when supported by the compiler. It is a platform independent library with no dependence and it officially supports the following compilers:
+- [*GCC*](http://gcc.gnu.org/) 4.7 and higher
+- [*Intel C++ Compose*](https://software.intel.com/en-us/intel-compilers) XE 2013 and higher
+- [*Clang*](http://llvm.org/) 3.4 and higher
+- [*Apple Clang 6.0*](https://developer.apple.com/library/mac/documentation/CompilerTools/Conceptual/LLVMCompilerOverview/index.html) and higher
+- [*Visual C++*](http://www.visualstudio.com/) 2013 and higher
+- [*CUDA*](https://developer.nvidia.com/about-cuda) 9.0 and higher (experimental)
+- [*SYCL*](https://www.khronos.org/sycl/) (experimental: only [ComputeCpp](https://codeplay.com/products/computesuite/computecpp) implementation has been tested).
+- Any C++11 compiler
+
+For more information about *GLM*, please have a look at the [manual](manual.md) and the [API reference documentation](http://glm.g-truc.net/0.9.8/api/index.html).

+interesting thing about it is the high degree of parallelism. All six
+lines with conditional expressions can be executed in parallel (on a
+machine with sufficient computational units).
+   Although the instruction count is 30 measured statically, it could
+execute in only 10 cycles on a machine with sufficient parallelism.

+; AutoExp.Dat - templates for automatically expanding data
+; Copyright(c) Microsoft Corporation. All Rights Reserved.
+;---------------------------------------------------------------
+;
+; While debugging, Data Tips and items in the Watch and Variable
+; windows are automatically expanded to show their most important
+; elements. The expansion follows the format given by the rules
+; in this file. You can add rules for your types or change the
+; predefined rules.
+;
+; For good examples, read the rules in this file.
+;
+; To find what the debugger considers the type of a variable to
+; be, add it to the Watch window and look at the Type column.
+;
+; An AutoExpand rule is a line with the name of a type, an equals
+; sign, and text with replaceable parts in angle brackets. The
+; part in angle brackets names a member of the type and an
+; optional Watch format specifier.
+;
+; AutoExpand rules use the following syntax. The equals sign (=),
+; angle brackets (<>), and comma are taken literally. Square
+; brackets ([]) indicate optional items.
+;
+; type=[text]<member[,format]>...
+;
+; type		Name of the type (may be followed by <*> for template
+;			types such as the ATL types listed below).
+;
+; text		Any text.Usually the name of the member to display,
+;			or a shorthand name for the member.
+;
+; member	Name of a member to display.
+;
+; format	Watch format specifier. One of the following:
+;
+;	Letter	Description					Sample		   Display
+;	------	--------------------------	------------   -------------
+;	d,i		Signed decimal integer		0xF000F065,d   -268373915
+;	u		Unsigned decimal integer	0x0065,u	   101
+;	o		Unsigned octal integer		0xF065,o	   0170145
+;	x,X		Hexadecimal integer			61541,X		   0X0000F065
+;	l,h		long or short prefix for	00406042,hx    0x0c22
+;			  d, i, u, o, x, X
+;	f		Signed floating-point		3./2.,f		   1.500000
+;	e		Signed scientific-notation	3./2.,e		   1.500000e+000
+;	g		Shorter of e and f			3./2.,g		   1.5
+;	c		Single character			0x0065,c	   'e'
+;	s		Zero-terminated string		pVar,s		   "Hello world"
+;	su		Unicode string				pVar,su		   "Hello world"
+;
+; For details of other format specifiers see Help under:
+; "format specifiers/watch variable"
+;
+; The special format <,t> specifies the name of the most-derived
+; type of the object. This is especially useful with pointers or
+; references to a base class.
+;
+; If there is no rule for a class, the base classes are checked for
+; a matching rule.
+;
+; There are some special entries allowed in the AutoExpand section:
+; $BUILTIN is used to display more complex types that need to do more
+; than just show a member variable or two.
+; $ADDIN allows external DLLs to be added to display even more complex
+; types via the EE Add-in API. The first argument is the DLL name, the
+; second argument is the name of the export from the DLL to use. For
+; further information on this API see the sample called EEAddIn.
+;
+; WARNING: if hexadecimal mode is on in the watch window, all numbers here are
+; evaluated in hex, e.g. 42 becomes 0x42

+<!-- 
+  GLM debugger visualizers for Visual Studio
+  
+  Makes debugging code using GLM easier by making data more easily accessible
+  from the debugger watch windows. 
+  
+  For example, a variable declared like this: 
+  
+  glm::vec4 v = glm::vec4(1, 2, 3, 4);
+  
+  Will show up like this in the default debugger windows:
+  
+   Name    Value
+  ..............................................................
+    v      {x=1.000000 r=1.000000 s=1.000000 y=2.000000 ...}
+  
+  But if you use this file, it will show up like this:
+  
+   Name   Value
+  ..................
+    v     [1 2 3 4]
+  
+  === How to Use ===
+  
+  Copy this file to the project directory of each project using GLM, or just copy it to
+  
+  %USERPROFILE%\Douments\Visual Studio 2019\Visualizers\ (replace '2019' when necessary)
+  or
+  %VSINSTALLDIR%\Common7\Packages\Debugger\Visualizers\ (requires admin access)
+  
+  if you want to use this from every project.
+  See also https://docs.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects

+/* stb_image_write - v1.16 - public domain - http://nothings.org/stb
+   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
+                                     no warranty implied; use at your own risk
+
+   Before #including,
+
+       #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+   in the file that you want to have the implementation.
+
+   Will probably not work correctly with strict-aliasing optimizations.
+
+ABOUT:
+
+   This header file is a library for writing images to C stdio or a callback.
+
+   The PNG output is not optimal; it is 20-50% larger than the file
+   written by a decent optimizing implementation; though providing a custom
+   zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
+   This library is designed for source code compactness and simplicity,
+   not optimal image file size or run-time performance.
+
+BUILDING:
+
+   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
+   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
+   malloc,realloc,free.
+   You can #define STBIW_MEMMOVE() to replace memmove()
+   You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
+   for PNG compression (instead of the builtin one), it must have the following signature:
+   unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
+   The returned data will be freed with STBIW_FREE() (free() by default),
+   so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
+
+UNICODE:
+
+   If compiling for Windows and you wish to use Unicode filenames, compile
+   with
+       #define STBIW_WINDOWS_UTF8
+   and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
+   Windows wchar_t filenames to utf8.
+
+USAGE:
+
+   There are five functions, one for each image file format:
+
+     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
+     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
+
+     void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
+
+   There are also five equivalent functions that use an arbitrary write function. You are
+   expected to open/close your file-equivalent before and after calling these:
+
+     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
+     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
+     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
+
+   where the callback is:
+      void stbi_write_func(void *context, void *data, int size);
+
+   You can configure it with these global variables:
+      int stbi_write_tga_with_rle;             // defaults to true; set to 0 to disable RLE
+      int stbi_write_png_compression_level;    // defaults to 8; set to higher for more compression
+      int stbi_write_force_png_filter;         // defaults to -1; set to 0..5 to force a filter mode
+
+
+   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
+   functions, so the library will not use stdio.h at all. However, this will
+   also disable HDR writing, because it requires stdio for formatted output.
+
+   Each function returns 0 on failure and non-0 on success.
+
+   The functions create an image file defined by the parameters. The image
+   is a rectangle of pixels stored from left-to-right, top-to-bottom.
+   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
+   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
+   The *data pointer points to the first byte of the top-left-most pixel.
+   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
+   a row of pixels to the first byte of the next row of pixels.
+
+   PNG creates output files with the same number of components as the input.
+   The BMP format expands Y to RGB in the file format and does not
+   output alpha.
+
+   PNG supports writing rectangles of data even when the bytes storing rows of
+   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+   by supplying the stride between the beginning of adjacent rows. The other
+   formats do not. (Thus you cannot write a native-format BMP through the BMP
+   writer, both because it is in BGR order and because it may have padding
+   at the end of the line.)
+
+   PNG allows you to set the deflate compression level by setting the global
+   variable 'stbi_write_png_compression_level' (it defaults to 8).
+
+   HDR expects linear float data. Since the format is always 32-bit rgb(e)
+   data, alpha (if provided) is discarded, and for monochrome data it is
+   replicated across all three channels.
+
+   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
+   data, set the global variable 'stbi_write_tga_with_rle' to 0.
+
+   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
+   Higher quality looks better but results in a bigger image.
+   JPEG baseline (no JPEG progressive).
