* 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)
* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0, ES 3.0)
* 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,
* When an internal state change is required all the stored vertex data is rendered in batch,
* additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch
*
* Some resources are also loaded for convenience, here the complete list:
