Most mysterious. On my computer (a standard Fedora Core 3
installation), Ipe became unusably slow (it would take 5 seconds for the
display to follow the cursor movement). Perhaps I should take out Ipe's
own rendering to bitmap and see what happens. I'd encourage all Linux
user's to comment out the following line in
"src/ipecanvas/ipecanvas.cpp" and report whether Ipe slows down
dramatically or whether it improves rendering without any problem:

That's not what I meant. You filed bug #130, but the same problem had
already been reported as bug #122 and bug #128.
