+*
+* raymath v2.0 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
+*
+* CONVENTIONS:
+* - Matrix structure is defined as row-major (memory layout) but parameters naming AND all
+* math operations performed by the library consider the structure as it was column-major
+* It is like transposed versions of the matrices are used for all the maths
+* It benefits some functions making them cache-friendly and also avoids matrix
+* transpositions sometimes required by OpenGL
+* Example: In memory order, row0 is [m0 m4 m8 m12] but in semantic math row0 is [m0 m1 m2 m3]
+* - Functions are always self-contained, no function use another raymath function inside,
+* required code is directly re-implemented inside
+* - Functions input parameters are always received by value (2 unavoidable exceptions)
+* - Functions use always a "result" variable for return (except C++ operators)
+* - Functions are always defined inline
+* - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
+* - No compound literals used to make sure libray is compatible with C++
+*
+* CONFIGURATION:
+* #define RAYMATH_IMPLEMENTATION
+* Generates the implementation of the library into the included file.
+* If not defined, the library is in header only mode and can be included in other headers
+* or source files without problems. But only ONE file should hold the implementation.
+*
+* #define RAYMATH_STATIC_INLINE
+* Define static inline functions code, so #include header suffices for use.
+* This may use up lots of memory.
+*
+* #define RAYMATH_DISABLE_CPP_OPERATORS
+* Disables C++ operator overloads for raymath types.

+*
+* rlgl v5.0 - A multi-OpenGL abstraction layer with an immediate-mode style API
+*
+* DESCRIPTION:
+* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0)
+* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
+*
+* ADDITIONAL NOTES:
+* When choosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
+* initialized on rlglInit() to accumulate vertex data
+*
+* When an internal state change is required all the stored vertex data is renderer in batch,
+* additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch
+*
+* Some resources are also loaded for convenience, here the complete list:
+* - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
+* - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
+* - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
+*
+* Internal buffer (and resources) must be manually unloaded calling rlglClose()
+*
+* CONFIGURATION:
+* #define GRAPHICS_API_OPENGL_11
+* #define GRAPHICS_API_OPENGL_21
