Description

This change improves the 'fullscreen' frame support on Windows. When going
to
fullscreen, the frame gets fullscreened with no window decorations (which
causes the
Windows task bar to also disappear) on the nearest monitor.

The old fullscreen functionality was actually 'maximize' behavior so I've
moved that to
'maximize'. 'fullwidth' and 'fullheight' are now ignored because they were
buggy (at least in
Windows 8, they were not being sized correctly) and are not common Windows
idioms.
While they could be supported, I'd do it as follow on work and get it
working right on
multiple monitors as well.

I've tested corner cases such as resolution changes and disconnect
monitors; in both
cases the fullscreen window stays fullscreen (and moves to a different
monitor for the
disconnect case).

I've modified the response to WM_WINDOWPOSCHANGED to do nothing when the
frame is fullscreen. Otherwise, the size gets tuned to a multiple of the
character cells and
the fullscreen isn't perfectly matching the screen. When this happens,
Windows' special
behavior to hide the taskbar doesn't kick in.

front.)
