Subject: 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.
