Cache the computed border size so we can fetch the border size at any time without worrying that we'll be spending too much time in the theme code (in some cases we might allocate a PangoFontDescription or do other significant work.) The main effort here is clearing the cache when various bits of window state change that could potentially affect the computed borders. https://bugzilla.gnome.org/show_bug.cgi?id=707194
