The fix in 786b589d95 for the
"Cannot click buttons more than once without moving the mouse cursor"
did not correctly handle setups with multiple screens in one display.
We need to handle the case where the first XQueryPointer returns
a different root window than the default one.
This fixes bug 597386 (agaion)
Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.

Backends that support native window background setting (and that clears
new window areas to this color/pixmap) should set this to true.
Currently only X11 supports this.
Fixed the prototypes of MyEnhancedXkbTranslateKeyCode() and
translate_keysym() to take a gint* because those functions treat
these arguments as an int, so we get around the need to cast.
We need to do a final XQueryWindow to get the coordinates inside the
windows rather than in the parent window.
This fixes bug #597386, "Cannot click buttons more than once...", which
failed due to the grab tracking stuff getting the wrong coordinates as
per the above.

This detection code is not 100% reliable, but it should fare much better
than the current code, which just compares the device name to a fixed
set of strings. Many applications depend on erasers being recognized
reliably, so we start by checking for a device name containing the
substring 'eraser'.

This has two advantages:
1) In many backends, this is faster as we can terminate the window
hierarchy traversal earlier
2) When used in gdkdisplay.c::get_current_toplevel() to get the
current toplevel that has the pointer we now correctly return
a toplevel with the pointer in it where the pointer is inside
some foreign subwindow of a toplevel window.
The second advantage fixes some bugs in client side event generation
when the pointer is inside such a foreign child window.
When filtering out the events for "window" from the events we got for
our "impl_window", don't forget to adjust the returned number of
events because it might be smaller than what XGetMotionEvents has
returned, and free coords we allocated too much. Also if we filtered
away *all* events, return FALSE and get rid of the allocated history
entirely. Together fixes all sorts of mishehavior when painting in
GIMP, from coords going wild to plain crashes and infinite loops.
The X11 queue_translation operation uses NextRequest to get the serial
of the XCopyArea operation where the translation should end. However,
if the gc passed to gdk_draw_drawable has a non-flushed clip region
(which it commonly has now for the window clipping) then the next
operation will be the GC flush, not the XCopyArea.
To handle this right we now pass in the GC to be used to
queue_translation and ensure that it is flushed before calling
NextRequest().
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.
X Bug report at:

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.
