Fixed Mac OS X so that window sizes do not include the titlebar and frame.
Wrote non-working code to get Windows to have Window sizes not count window decoration. Technically it does work, but it doesn't seem to fix Area scrollbars... which reminds me, the default configuration for the keyboard test exhibits the "last pixel" but mentioned in one of the TODOs in area_windows.go on both scrollbars, so let's fix that first anyway. I'll move the TODO for window decoration to the future plans after I get a definite answer about GTK+'s behavior.
Ensured that pressing Modifiers+Key/ExtKey does not produce an event with just the Key/ExtKey.
Clarified the previous commit.
More TODOs.
More TODOs.
Removed the Windows Area resizing glitches TODOs... as they seemed to have gone away on their own (GDI+ issue that no longer applies since I dropped GDI+?).
Added click-to-focus to GTK+ Areas and documented that click-to-focus happens; also TODOs related to that.
Settled window sizing for GTK+; moved the respective TODO to future plans.
