Description Anders Carlsson 2001-07-07 13:55:59 UTC 
There's no way to get the backing store pixmap from a GdkWindow, which
makes it impossible to use X functions to draw on the window during
exposes. Owen suggested something like   gdk_window_get_paint_info (window,
drawable **real_drawable, GdkRegion **bounds)

	* gdk/gdkwindow.[ch]: Add a function gdk_window_get_internal_paint_info(),
	so that using X functions on a GdkWindow is possible, if
	a little hairy.

	* gdk/gdkgc.c (gdk_gc_offset): Add a function to offset the clip
	and ts_origin of a GC, so that external parties can offset/restore
	a GC, when using gdk_window_get_internal_paint_info().
