Alpha is 8 bits. SGI's Infinite Reality2 engine only has
12 bit alpha. I think you'll see framebuffers go floating point
before you get larger alpha.
Basically, for cheesy desktop translucency effects (there are no
other types), 8 bits is more than enough. Using more is, as
Raster claims, a waste of bandwidth.
