* rlgl - raylib OpenGL abstraction layer
*
* 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).
* rlgl is a wrapper for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0) to
* pseudo-OpenGL 1.1 style functions (rlVertex, rlTranslate, rlRotate...).
*
* 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:
