Richard Hult 571c460503 Always set success to TRUE. (gdk_color_change): Implement.
2006-07-29  Richard Hult  <richard@imendio.com>

	* gdk/quartz/gdkcolor-quartz.c (gdk_colormap_alloc_colors): Always
	set success to TRUE.
	(gdk_color_change): Implement.

	* gdk/quartz/GdkQuartzWindow.c
	([GdkQuartzWindow -canBecomeKeyWindow]): Add comment.

	* gdk/quartz/gdkevents-quartz.c (gdk_screen_get_setting): Make the
	default font a bit smaller until we have made this get the system
	setting.

	* gdk/quartz/gdkwindow-quartz.c (gdk_window_set_type_hint): Enable
	shadows for the right window types.

	* gdk/quartz/gdkprivate-quartz.h:
	* gdk/quartz/gdkgc-quartz.c:
	* gdk/quartz/gdkdrawable-quartz.c:
	* gdk/quartz/gdkcolor-quartz.c: Expose the CGContext functions,
	update callers.

	* gdk/quartz/gdkmain-quartz.c: (_gdk_windowing_init): No need to
	get the current process ID, use the right constant instead.
