Of course, but:
* I want to use gtk
* My need is not limited to screen snapshots
* I use one X server which manage two screens in the classical way (not
Xinerama): there are two separate X displays: :0.0 and :0.1.

My idea was to have **gtk** manage two display connexions (two XOpenDisplay, two
ressources set associated with the displays (colors,...) two blocking-listening
for an XEvent- XNextEvent in two separate threads... but threads brings lots of
difficulties).
