In <X11/Xlib.h>: int ScreenCount(Display *dsp);

Performer apps generally assume that multi-pipe systems are laid out
with (in Xlib terms) a single Display and multiple screens, e.g.
$DISPLAY strings :0.0, :0.1, :0.2 would represent the 3 screens of a 3
pipe system.

There are exceptions (in Xlib terms: 3 Displays, 1 screen each) but
this usually implies three separate users, so performer assumes it to be
a 1-pipe system (for each user). Folks who want to override this have
to put it in code explicitly.
