Bug 652629 - GnomeCanvas: Disregard synthesized crossing events
synth_crossing() in gtkwidget.c does not set valid pointer coordinates,
but GnomeCanvas relies on these coordinates to figure out what canvas
item the event applies to.
Detect these synthesized GDK_ENTER_NOTIFY and GDK_LEAVE_NOTIFY events
and disregard them.
This was breaking drag-and-drop of EMinicards and probably elsewhere.
