-- raylib [textures] example - texture formats loading (compressed and uncompressed)

-- 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 1.6 (www.raylib.com)
