Subject: Allows the popup to be displayed below as long as it can fit on the
 monitor the cursor is on rather than flipping up above the current point when
 near bottom of window. Implemented for GTK+ by John Ehresman. Partial Windows
 implementation #ifdefed out because it uses calls unavailable on Windows 95.
