------- Additional Comments from Kalev Lember <kalevlember at gmail.com>
The widget backing store was created in size_allocate() before the
widget was realized. This wasn't a problem for GtkWidgetBackingStoreX11,
but WidgetBackingStoreCairo's constructor needs the widget's GDK window,
which is is created in realize().

Fixes the WebKitWebView not painting on platforms that use
WidgetBackingStoreCairo, e.g. win32.
