Clearing will directly modify the contents of the window, so we need
to flush any outstanding moves or double-buffering.
(cherry picked from commit 8c1ea38d84)
Run gtk_icon_view_layout() if necessary before attempting to paint the
icon view items during an expose event. This ensures all the items have
valid sizes, as some themes don't take kindly to negative dimensions.
Previously the filename would get re-set on the button if one cleared the selection,
as an async cancellable was not getting canceled in that case. Patch with

The root window width and height have already been correctly
initialised in _gdk_root_window_size_init() to cover all monitors, so
don't incorrectly re-initialise using GetSystemMetrics(SM_C[XY]SCREEN)
which only gives the size of the primary monitor anyway. (See MSDN.)
This fixes at least gdk_screen_get_{width,height}() which indirectly
affects at least the positioning of combo box pop-up menus on multiple
monitors.
When GtkMisc padding is set on an image, the optimization for only
recalculating size after a clear() breaks, since the requisition is
not (0, 0). We need a separate 'need_calc' flag.
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.
