* rlgl - raylib OpenGL abstraction layer
*
* raylib now uses OpenGL 1.1 style functions (rlVertex) that are mapped to selected OpenGL version:
* OpenGL 1.1 - Direct map rl* -> gl*
* OpenGL 2.1 - Vertex data is stored in VBOs, call rlglDraw() to render
* OpenGL 3.3 - Vertex data is stored in VAOs, call rlglDraw() to render
* OpenGL ES 2 - Vertex data is stored in VBOs or VAOs (when available), call rlglDraw() to render
* rlgl allows usage of OpenGL 1.1 style functions (rlVertex) that are internally mapped to
* selected OpenGL version (1.1, 2.1, 3.3 Core, ES 2.0).
*
* When chosing an OpenGL version greater than OpenGL 1.1, rlgl stores vertex data on internal
* VBO buffers (and VAOs if available). It requires calling 3 functions:
* rlglInit() - Initialize internal buffers and auxiliar resources
* rlglDraw() - Process internal buffers and send required draw calls
* rlglClose() - De-initialize internal buffers data and other auxiliar resources
*
* External libs:
* raymath - 3D math functionality (Vector3, Matrix, Quaternion)
* GLAD - OpenGL extensions loading (OpenGL 3.3 Core only)
*
* Module Configuration Flags:
* GRAPHICS_API_OPENGL_11 - Use OpenGL 1.1 backend
* GRAPHICS_API_OPENGL_21 - Use OpenGL 2.1 backend
* GRAPHICS_API_OPENGL_33 - Use OpenGL 3.3 Core profile backend
* GRAPHICS_API_OPENGL_ES2 - Use OpenGL ES 2.0 backend
*
* RLGL_STANDALONE - Use rlgl as standalone library (no raylib dependency)
