* NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
* OpenGL 1.1 does not support shaders but it can also be used.
*
* Compile rlgl module using:
* gcc -c $(RAYLIB_DIR)\raylib\src\rlgl.c -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33 /
* -I$(RAYLIB_DIR)\raylib\src\external -Wall -std=c99
* 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
*
* NOTE: rlgl module requires the following header-only files:
* external/glad.h - OpenGL extensions loader (stripped to only required extensions)
* shader_distortion.h - Distortion shader for VR
* raymath.h - Vector and matrix math functions
* 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).
*
* Compile example using:
* gcc -o rlgl_standalone.exe rlgl_standalone.c rlgl.o -s $(RAYLIB_DIR)\raylib\raylib.rc.o -I$(RAYLIB_DIR)\raylib\src /
* -L. -L$(RAYLIB_DIR)\raylib\src -lglfw3 -lopengl32 -lgdi32 -Wall -std=c99
* COMPILATION:
* gcc -o rlgl_standalone.exe rlgl_standalone.c -s -Iexternal\include -I..\..\src \
* -L. -Lexternal\lib -lglfw3 -lopengl32 -lgdi32 -Wall -std=c99 \
* -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33
