(Part 2)
* gdk/gdkprivate.h: Remove gdk_*_lookup() defines, since they are defined by the
individual backends already.
* gdk/gdkregion-generic.h, gdk/gdktypes.h: Put gdkregionbox & gdksegment back together
again. Yes, there really is a good reason for this, if you are using the gdkregion
internals, and if you're not, why do you care?
* gdk/gdkwindow.c: Fix inverted condition
* gdk/linux-fb: Compiles (for me - it will not work elsewhere most likely).
* gtk/gtkcolorsel.c, gtk/gtkwindow.c: Add include for linux-fb
* gtk/gtkrange.c: Redraw trough when moving.
* gtk/gtktypeutils.c: Fix warning by adding const cast.
* modules/linux-fb/basic.c: Fix unknown glyph retrieval.
