I assume the same (i.e. non-zero alpha values mandating alpha in the BMP image formats) applies to the other compressed texture formats, right? Yeah, I think I limited it to DXT2 to avoid adding extra tests because I already felt like there might be too many. I've added similar tests now for DXT3-DXT5. DXT1 is different because of the way its encoded, it's not as simple as just setting the entire thing to `0xff`. I can add a test for DXT1 having all 0 alpha values if you feel it's necessary, but it's a bit more of a hassle. :)
