-*
-* raylib [rlgl] example - Using rlgl module as standalone module
-*
-* 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 rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33
-*
-* Compile example using:
-* gcc -o $(NAME_PART).exe $(FILE_NAME) rlgl.o -lglfw3 -lopengl32 -lgdi32 -std=c99
-*
-* This example has been created using raylib 1.5 (www.raylib.com)
-* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
