+/*******************************************************************************************
+*
+* raylib [shaders] example - Apply a shader to a 3d model (adapted for HTML5 platform)
+*
+* 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)
