(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.
