xmen_1024 encoded to .basis at various bitrates

Here's xmen_1024 compressed at various bitrates to .basis. I show the output of two transcodes: ETC1 (which is the highest quality format in baseline .basis) and PVRTC (with clamp addressing).

Original:

Optimal ETC1 is 38.896 Y PSNR

Q 16: .717 bits/texel, ETC1 28.473 Y PSNR
