-*
-* raymath v1.5 - 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
-* - 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.

-* rlgl v4.5 - 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
-* #define GRAPHICS_API_OPENGL_33
-* #define GRAPHICS_API_OPENGL_43
-* #define GRAPHICS_API_OPENGL_ES2
-* #define GRAPHICS_API_OPENGL_ES3
-* Use selected OpenGL graphics backend, should be supported by platform
-* Those preprocessor defines are only used on rlgl module, if OpenGL version is
-* required by any other module, use rlGetVersion() to check it
-*
-* #define RLGL_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 RLGL_RENDER_TEXTURES_HINT
-* Enable framebuffer objects (fbo) support (enabled by default)
-* Some GPUs could not support them despite the OpenGL version
-*
-* #define RLGL_SHOW_GL_DETAILS_INFO
-* Show OpenGL extensions and capabilities detailed logs on init
-*
-* #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT
-* Enable debug context (only available on OpenGL 4.3)
-*
-* rlgl capabilities could be customized just defining some internal
-* values before library inclusion (default values listed):
-*
-* #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits
-* #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering)
-* #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture)
-* #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture())
-*
-* #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack
-* #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported
-* #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance
-* #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance
-*
-* When loading a shader, the following vertex attributes and uniform
-* location names are tried to be set automatically:
-*
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Bound by default to shader location: 0
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD "vertexTexCoord" // Bound by default to shader location: 1
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL "vertexNormal" // Bound by default to shader location: 2
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR "vertexColor" // Bound by default to shader location: 3
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TANGENT "vertexTangent" // Bound by default to shader location: 4
-* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD2 "vertexTexCoord2" // Bound by default to shader location: 5
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MODEL "matModel" // model matrix
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_NORMAL "matNormal" // normal matrix (transpose(inverse(matModelView))
-* #define RL_DEFAULT_SHADER_UNIFORM_NAME_COLOR "colDiffuse" // color diffuse (base tint color, multiplied by texture color)
-* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE0 "texture0" // texture0 (texture slot active 0)
-* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE1 "texture1" // texture1 (texture slot active 1)
-* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE2 "texture2" // texture2 (texture slot active 2)
-*

-* - OpenGL libraries (depending on platform and OpenGL version selected)
-* - GLAD OpenGL extensions loading library (only for OpenGL 3.3 Core, 4.3 Core)
