 *   rlgl - raylib OpenGL abstraction layer

-*   raylib now uses OpenGL 1.1 style functions (rlVertex) that are mapped to selected OpenGL version:

-*       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
