Use @synthesize instead?

Done. (in https://codereview.chromium.org/329743002/)

It would be great to optimize this to use dirtyRect.

[tapted, 2014/06/12 09:09:38]

At this call site, it should be clipped by the canvas in View::Paint - but
you're quite right that I'll need to do this at the other side of the bridge; in
NativeWidgetMac (which also needs a coordiate transform) (see
https://codereview.chromium.org/329743002/diff/70001/ui/views/widget/native_w...
).
