Work around https://bugs.freedesktop.org/show_bug.cgi?id=4320,
which used to be our own
http://bugzilla.gnome.org/show_bug.cgi?id=314616. If one uses a
pixmap for a pattern in Cairo, and sets the pattern to
CAIRO_EXTEND_REPEAT; and if the destination surface is also a
pixmap, Cairo does a slow copy instead of using XCopyArea(). So,
we use the same code that we used in GTK+ 2.6 (pre-cairo), by
filling the double-buffer pixmap with a tiled GC and
XFillRectangle().
* gdk/gdkwindow.c (BackingRectMethod): New structure with a
cairo_t and a GdkGC field. Depending on which of these fields
gets filled in, we'll use Cairo or GDK to clear the double-buffer
pixmap when painting a window.
(setup_backing_rect_method): Fill a BackingRectMethod as
appropriate, depending on the window's configuration and our
knowledge of whether Cairo is fast or slow when doing repeating
patterns.
(gdk_window_clear_backing_rect): Call
setup_backing_rect_method(). Depending on what it returns, use
Cairo to clear the double-buffer pixmap, or plain GDK.
