* gtk/gtkentry.c gtk/gtkimcontextsimple.c gtk/gtklabel.c
gtk/gtktexttypes.c gtk/testtext.c modules/linux-fb/basic.c:
Remove use of libunicode in favor of new GLib functions.
* gtk/gtkcolorsel.c: Remove conditional includes for FB, win32,
nano-x, framebuffer. The X11 include is just a hack until we get
the necessary functions in gdkcolor.h, so there is no reason to
add other includes of platforms.
* gtk/gtkwindow.c (gtk_window_compute_default_size): Revert
window bigger than the screen change.
* gtk/testgtk.c: Revert some random changes from Elliot
that had no particular point and were causing testgtkrc
not to function correctly.
* gdk/gdkregion-generic.h: Revert change from Elliot. Just
because GdkSegment and GdkRegionBox have the same fields,
it doesn't mean that 'typedef GdkSegment GdkRegionBox'
results in clearer code.
* gdk/x11/gdkinput-x11.c (gdk_input_common_select_events,
gdk_input_translate_coordinates): Fix missed GdkObjectification
