Well, when you generate an image with alpha-channel you get a 32-bit image.
Only PNG supports more than 8 bpc, however, no program seems to support more
than that (they reduce it to 8 bit again). And at least one program (the PNG
import plug-in for PhotoShop 4.0 on the Mac) seem to have/had problems with
PNG images over 8 bpc and an alpha-channel...
