Dear Apps,

Let me indulge in a brief clarification:

I was talking about *lossy* compression and an alpha channel, which
is something we can't do yet in HiPS (unless you count compressed
FITSes and NULL pixels are rendered transparent -- and even then you
don't have the blending you have with an actual alpha channel).
