bug#2530: 23/NS: redraws according to mouse-face are slow

I find that the redisplay of overlays that happens when the mouse is moved into an overlay with a mouse-face property are much slower in Emacs 23 (NS, under Cocoa/OS X). It is pretty much a nasty animation - every layer is redrawn from left to right, it seems, and every step is visible. It seems that background is drawn first, and then the text over it.

The overlays I am working with are in the header-line; I'm using (an adapted version of) tabbar.el for this. The resulting package is a not stand-alone and I'd have a hard time turning it into a small test case; before I work on this, I'd rather ask here if this problem is a known one.

I have experimented with calls to NSDisableScreenUpdates () in ns_update_begin, ns_update_window_begin and ns_focus, but that didn't help at all.
