Attached is a comparison of the input and decoding with DXT4 and DXT5.
DXT5 produces dark outlines that are not present in the input.
Also, I have a prototype "Normal Quality, With Alpha" encoder that produces
nasty results in Resolume unless alpha is premultiplied. All of this points
to DXV misnomering DXT5.
