This is more important in the client side windows world, as clip masks
may be used for clipping to non-native subwindows. This fixes a bug
in aisleriot where it uses masked pixbuf drawing and it ends up drawing
over the moving card subwindow.
Turns out pygtk build broke due to the argument addition to draw_drawable.
So, we now add a new vfunc for the new draw_drawable and are thus
backwards compat.
Last commit was bad, as it didn't clip against client side
children. This implements such clipping first and then
only clears the rectangles that need to be cleared.
Without this we can't draw to them, which caused problems for e.g.
gnome-settings-daemon clearing the background when the desktop
background changed.
Note: We don't actually clip away child windows from the root window,
the clip is just based on the size of the root window.
Use g_*gettext functions in gdk-pixbuf instead direct gettext
calls to benefit from the maybe-dont-translate functionality
in GLib. Also, replace a hand-rolled version by g_dpgettext2
in gtkbuilderparser.c. Fixes bug 585791.
We want to be able to map any window coordinate to a root coordinate, not
just the origin, because you can't rely anymore on a simple translation
from window coordinates to parent with offscreen windows. This lets
us e.g. pop up menus in the right place even if they are popped up from
a no-window widget.
This also removes the (unimplemented) possibility to change a window to
non-native. This seems generally not very useful, and there are some problems
with it, for instance if two "users" need a window to be native and then
one of the "users" doesn't need it anymore it can't change it back, because
it is unaware of the other reason the window is native.
Calling gdk_window_get_events() had the side-effect of letting
property change notification through to the application, which
was not intended. Now we keep StructureNotify and PropertyNotify
filtered out when they were before. Reported in bug 582003.
Change gdk_window_set_icon_name to allow using NULL to unset a
previously set icon title, so that the icon title tracks the normal
title again. Bug #535557.
When RandR 1.2 X driver doesn't return any usable multihead data the
monitors array is freed, without freeing the memory allocated by the array
elements before. Fixes bug #578354
It turns out that XCopyArea handling of obscured source regions is
buggy. It clears the destination area even outside the GC clip
region. We work around this for the pixmap->window case as that
can happen in gtk+ and is easy to work around.

To avoid drawing the window background of other windows in the area
where the window was we set the bg to none recursively. However, this
is quite costly it the moved window has many siblings. Furthermore, it
is uncommon that siblings overlap, so this cost has little gain.
So, we only set bg None on the parent, which means that there will
be some more flicker in the uncommon case of overlapping siblings.
