gdk_display_get_n_screens() will tell you how many non-xinerama screens
there are, and gdk_screen_get_n_monitors() on each screen will tell
you how many monitors make up that particular xinerama screen.

see the gdk API docs for details:
http://developer.gnome.org/doc/API/2.0/gdk/
(specifically, the Multi-head Support Overview and the API docs on
GdkDisplay and GdkScreen).  note that this requires gtk 2.2 at minimum;
otherwise you'll need to use some Xlib functions, as well as checking
for the presence of and enabled/disabled state of the xinerama extension.
