* raylib [textures] example - texture formats loading (adapted for HTML5 platform)
|

*
|

* NOTE: This example requires raylib OpenGL 3.3+ or ES2 versions for compressed textures,
|
||||
* OpenGL 1.1 does not support compressed textures, only uncompressed ones.
|
||||
*
|
||||
* 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)
