* gtk/gtkwidget.c: Add a draw-border style property to allow
themes to draw outside the widget's allocation.
* gdk/gdkwindow.c gtk/gtkstyle.c: Remove some save/restore pairs
that were working around the clip-leakage bug in Cairo.
* gtk/gtkstyle.c: Use cairo_fill_preserve() rathe than
save/fill/restore.
* gdk/gdkgc.c gdk/gdkinternals.h: Add _gdk_gc_update_context()
That updates a Cairo context to match a GC.
* gdk/gdkdraw.c: Use _gdk_gc_update_context() to add support
for tiles/stipples/clipping to gdk_draw_glyphs(),
gdk_draw_trapezoids().
* gdk/gdkpango.c: Use _gdk_gc_update_context() instead of internal
implementation of stipples. Use one cairo_t across the entire
drawing operation. Replace cairo_matrix_create() with
stack-allocated matrices.
* gdk/gdkgc.c gdk/gdkinternals.h gdk/x11/gdkgc-x11.c
gdk/win32/gdkgc-win32.c: Save various aspects of the
GC state (fill, tile, stipple, foreground, background, clip region)
in instance-private-data for future use. Add getters.
Get rid of _gdk_windowing_gc_get_foreground() function implemented
by the backends.
* gdk/gdkgc.c gdk/gdkinternals.h gdk/x11/gdkgc-x11.c
gdk/win32/gdkgc-win32.c gdk/linux-fb/gdkgc-fb.c: Add
_gdk_gc_init() to do initial setup of the GC from values;
fixes some problems from drawable redirection.
* gdk/gdkgc.c gdk/gdkinternals.h gdk/x11/gdkgc-x11.c
gdk/win32/gdkgc-win32.c gdk/linux-fb/gdkgc-fb.c: Move
gdk_gc_copy() and gdk_gc_set_clip_{region,rectangle}() into
the generic code, add _gdk_windowing_gc_copy(),
_gdk_windowing_gc_set_clip_region() to do backend specific
stuff.
* gdk/x11/{gdkprivate-x11.h,gdkgc-x11.c.c,gdkdrawable-x11.c}
gdk/win32/{gdkprivate-win32.h,gdkgc-x11.c.c,gdkdrawable-x11.c}
gdk/linux-fb/{gdkprivate-fb.h,gdkgc-fb.c.c,gdkdrawable-fb.c}:
Don't duplicate state that now is stored by the generic code.
* gdk/gdk.symbols Update
