i've stumbled upon this many times since the xscreensaver hacks use
pixel mangling routines so much...  i don't know what the right
solution is, except that loadimage is really slow (and it hits you
really bad whenever the display isn't on the same machine as the
program, drawterm for example).  i know aki nyrhinen did some work on
increasing the bulk transfer for loadimage, but that's about it.

point2rgb seemed like the simplest solution (with rgb2point on the
other hand), but i am now convinced it would be, again, painfully slow
on remote displays.

this situation is rarely seen in the real world :)
