Very basic global Reinhard tone mapping, output converted to sRGB with no dithering, alpha is carried through unchanged. Only used for debugging/devel

The .astc texture format is readable using ARM's astcenc, AMD Compressonator, and other engines/tools. It oddly doesn't support mipmaps, limiting its
