It's the window without the menubar (the top one that is always there on
Mac OS X, sort of like the Windows taskbar that is always at the
bottom), but not accounting for the menubar on individual X windows.
It's just the "usable space" for the monitor. If you could create a
graphics window without a menubar, you could use all that space.

My screen resolution is 1680 x 1050:

IDL> print, get_screen_size()
1680 1028

This, as well as using IDLsysMonitorInfo::getRectangles(), returns the
same thing:

IDL> Device, Get_Screen_Size=theSize
IDL> print, thesize
1680 1028
