NAME
X11::Xlib::Screen - Convenience wrapper around Display+ScreenID
DESCRIPTION
In ancient history, a Screen represented one physical graphics device + monitor. Now days there tends to be only one per system, with multiple monitors or displays aggregated into a single screen using Xinerama or XRandR. This was mostly caused by the annoying restriction that graphic resources (i.e. windows) are bound to a single screen.
The short of that story is that $display->screen_count and $screen->width etc don't do what a person might expect them to do. If you want to know about the boundaries of physical monitors you'll need the yet-unwritten X11::Xlib::Monitor objects provided by a future wrapper around Xinerama or XRandR.
