Color comprimido con formato de textura de canal alpha.
DXT5 format compresses textures to 8 bits per pixel, and is widely supported on PC, console and Windows Phone platforms.
It is a good format to compress most of RGBA textures. For RGB (without alpha) textures, DXT1 is better. When targeting DX11-class hardware (modern PC, PS4, XboxOne), using BC7 might be useful, since compression quality is often better.
