*
* raylib [rlgl] example - Using rlgl module as standalone module
*
* NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
* rlgl library is an abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, ES 2.0)
* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
*
* NOTE: This example requires OpenGL 3.3 or OpenGL ES 2.0 for shaders support,
* OpenGL 1.1 does not support shaders but it can also be used.
*
* DEPENDENCIES:
* rlgl.h - OpenGL 1.1 immediate-mode style coding translation layer
* glad.h - OpenGL extensions initialization library (required by rlgl)
* raymath.h - 3D math library (required by rlgl)
* glfw3 - Windows and context initialization library
*
* rlgl library is provided as a single-file header-only library, this library
* allows coding in a pseudo-OpenGL 1.1 style while translating calls to multiple
* OpenGL versions backends (1.1, 2.1, 3.3, ES 2.0).
* rlgl.h - OpenGL abstraction layer to OpenGL 1.1, 3.3 or ES2
