/*******************************************************************************************
*
* raylib [shaders] example - Apply a shader to a 3d model
*
* NOTE: This example requires raylib OpenGL 3.3 or ES2 versions for shaders support,
* OpenGL 1.1 does not support shaders, recompile raylib to OpenGL 3.3 version.
*
* NOTE: Shaders used in this example are #version 330 (OpenGL 3.3), to test this example
* on OpenGL ES 2.0 platforms (Android, Raspberry Pi, HTML5), use #version 100 shaders
* raylib comes with shaders ready for both versions, check raylib/shaders install folder
*
* This example has been created using raylib 1.3 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
