[PATCH] bitmap-region conversion and shaped windows

[Ron Steinke <rsteinke w-link net>]

	I've uploaded two new patches to ftp.gtk.org,
gtk-rsteinke-001222-2.patch and gtk-rsteinke-001222-3.patch
(There are no -0 and -1 patches, I had an interrupted upload).
gtk-rsteinke-001222-2.patch replaces gtk-rsteinke-001205-1.patch.
It fixes some bugs in gdk_bitmap_create_from_region.
gtk-rsteinke-001222-3.patch implements two new functions,

void gdk_window_shape_combine_rectangles (GdkWindow *window,
                                          GdkRectangle *rectangles,
                                          gint nrectangles,
                                          gint offset_x,
                                          gint offset_y);
void gdk_window_shape_combine_region     (GdkWindow *window,
                                          GdkRegion *region,
                                          gint offset_x,
                                          gint offset_y);

These work the same as gdk_window_shape_combine_mask, except they
use an array of GdkRectangle or a GdkRegion, respectively. This
patch also includes changes on the back end, so that the implementation
dependent code only has to implement one of the three
gdk_window_shape functions. Note that I've only tested this under X,
so I'd be grateful if someone could test the other implementations.
The win32 and linux-fb implementations should be fine, since
they're implemented in a similar enough way to x11. I would particularly
like someone to look at the nanox implementation. If you run it
and get something like "unimplemented gdk_window_impl_nanox_shape_combine_mask",
you're hitting the nanox function stub, and everything's fine.
If you get "Shaped windows not implemented." or a seg fault, I'm
defining the values of some pointers to functions in the wrong
place.

gtk-rsteinke-001222-2.patch requires gtk-rsteinke-001205-0.patch,
and gtk-rsteinke-001222-3.patch requires both gtk-rsteinke-001205-0.patch
and gtk-rsteinke-001222-2.patch.
