* gdk/{gdkdrawable.[ch],gdkpixmap.c,gdkwindow.c,x11/gdkwindow.c}:
Add two virtualized functions gdk_drawable_get_clip_region - to
get the clip region when drawing.
* gdk/gdkwindow.c (gdk_window_invalidate_rect): Rewrite to simple
use invalidate_region.
* gdk/gdkwindow.c (gdk_window_invalidate_region): Clip to visible
region.
* acconfig.h configure.in: Check for Xft. For now, assume
that if Xft is found, Pango was compiled with Xft support
as well.
* gdk/gdkcolor.h gdk/x11/gdkcolor-x11.c: Add
gdk_colormap_query_color().
* gdk/x11/gdkdrawable-x11.c (gdk_x11_draw_glyphs): Draw
with Xft if appropriate.
* gdk/x11/gdkpango-x11.c (gdk_pango_context_get): Create
a pangoxft context if we have XFT and the environment
variable GD_USE_XFT is set.
* gdk/x11/gdkx.h (struct _GdkGCX11): Cache the fg_pixel
and also possibly an XftDraw structure.
* gtk/gtkfontsel.c: Handle the case where the font from the
style doesn't match any of the fonts a bit better.
* gtk/testgtk.c: Add tabs between directional segments for
hebrew/arabic test. (Not really necessary, just a little
prettier.)
