Zero width/height is unsupported and will magically be turned into one.
For instance, gtk_widget_size_allocate() will eventually do this magic
on the value stored in widget->allocation.
However, if we don't do this magic conversion early, then the value
returned from gtk_window_compute_configure_request() will not be
comparable with whats stored in widget->allocation. (I.E. they will
differ if width or height are zero).
This is dangerous, as we do such a comparison in gtk_window_move_resize().
Currently a change from e.g. 10x1 (current allocation) to 10x0 (new size)
will be expected to produce a ConfigureNotify, when it actually won't,
thus never thawing the frozen toplevel.
Fixes bug #588059
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.
Thanks gcc :

The convention for landscape pages, and required by PostScript
Language Reference Manual, is for landscape printing to rotate user
space 90 degrees counterclockwise. Part of bug 596423
Like the other GtkSettings already registered, these are influenced from
the outside and cannot be properly tested. The defaultvalues test
passes again now.
gtk_tree_model_build_level() always needs to emit row-inserted when
requested, this should not depend on whether the level has a parent
level or a virtual root, which is a check whether or not we need to
reference the node in the child model. Furthermore, we also need
to emit row-has-child-toggled after row-inserted when appropriate.
When gtk_tree_model_filter_row_changed() pulls in the root level, it
must request build_level() to emit signals for this. The refilter
function uses row_changed to process the changes, so build_level() in
the first call to row_changed() might pull in multiple new nodes in this
scenario, for all of these signals need to be emitted. Of course,
build_level() will then also emit the signals for the node row_changed()
is processing, we should not emit a duplicate signal, this is now
accounted for.
Add a unit test for this. For this small functionality to block the
row-changed signal has been implemented, so that we can simulate calls
to the refilter function using the current visible column setup.
_gtk_tooltip_handle_event, which is called for many events in the GTK+
main loop, calls gtk_tooltip_set_last_window, which keeps a weak
reference to the last window we passed through. If the window being
set is the same than the last one there's really no need to update our
weak reference, so add a check for that and exit early.
These event types propagate up the hierarchy anyway, so this means
we avoid setting it unnecessarily. This is especially important
for button press event, since only one client can select for this
on each window, causing X errors if two clients do it.
