Andreas Kling 432ab47053 WindowServer: Allow partial repaints in window frame & menubars ...

Before this change, invalidating any rect in a WindowFrame would cause
the entire window (including frame & drop shadow) to get invalidated,
leading to copious amounts of overdraw when mousing over menubars,
titlebars, and window buttons.

We now simply allow the partial frame invalidations through to the
window's dirty rects collection and the compositor takes care of it.
