Add a draw-border style property to allow themes to draw outside the

Browse Source 
2005-04-28  Owen Taylor  <otaylor@redhat.com>

	* 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/win32/gdkgc-win32.c gdk/linux-fb/gdkgc-fb.c: Move

	the generic code, add _gdk_windowing_gc_copy(),
	_gdk_windowing_gc_set_clip_region() to do backend specific
	stuff.
