Evidently, imlib thinks my X server has 24 bit color, when it actually has
16. I tried turning the display up to 24 bits, but it didn't help. I hacked
rend.c to force imlib to use 16 bits and it works, except the colors are
wrong, which is understandable.

So, it appears that I'm suffering a problem that doesn't rightly belong to
us 16 bit users.

There's been some talk about this maybe being an endianness issue. I don't
think so. Both my machines are Pentiums.

BTW, could anybody tell me why panel uses gdk_imlib, and
background-properties uses Imlib?

A side note: testgtk -> ctree -> sort -> crash
...and since I'm in a backtrace kinda mood...

First impression of the running GNOME (finally!):
The panel clock flashes annoyingly (only on a remote x server).
