How can I ask the X server (V11) for his preferential image format ?
(I mean XYPixmap or ZPixmap).
for instance, on SUN 3 with 8 bits color display, it take 250 times longer
with XYFormat than with ZFormat to get a 128x128 XImage from the server.
On my DPX1000 display with 2 planes, the situation is inverted.
for the moment, I've add a "-z" option on the command line but if I can
remove it ...

You can't. There are many, many "performance" criteria that applications
might like to know about, but I've never seen a workable proposal for how
to convey this information in a reasonable fashion.
