Implement lots of value setters for GdkGC, based on a heavily modified

       Implement lots of value setters for GdkGC, based on a heavily
       modified patch from Thomas Broyer (bug #328853):

	* gdk/quartz/gdkcolor-quartz.c: removed functions which set colors
	on the CGContext. Instead, added gdk_quartz_get_rgba_from_pixel()
	which simply returns RGBA values from a GdkColor's pixel value.
	See gdk_quartz_update_context_from_gc() below.

	* gdk/quartz/gdkprivate-quartz.h (struct GdkGCQuartz): added lots
	of members for the newly suppored GC values. Added enum
	GdkQuartzContextValuesMask which is used for setting up the
	CGContext for filling and/or stroking.

	* gdk/quartz/gdkgc-quartz.c (gdk_quartz_gc_get_values)
	(gdk_quartz_gc_set_values)
	(_gdk_windowing_gc_copy): support a lot more GC values.

	(gdk_quartz_update_context_from_gc): added
	GdkQuartzContextValuesMask parameter and set filling/stroking
	parameters accordingly. This function also gained full control
	over the FG and BG colors (they can't be set separately any more).

	The stipple mask part of the patch doesn't work but seems to take
	the right approach and doesn't make things worse, so I applied it.

	Did *not* apply the clipping part of the patch since I don't
	understand it (I don't understand the version in CVS either, but
	it at least works :-)

	* gdk/quartz/gdkdrawable-quartz.c: pass the right masks to
	gdk_quartz_update_context_from_gc() and removed separate color
	setting calls. Some minor fixes.

	* gdk/quartz/gdkwindow-quartz.c
	(gdk_window_impl_quartz_begin_paint_region): set the CGContext's
	fill color manually. We don't have/need a GC here.
