Subject: [PATCH] Don't draw size grip on Mac > 10.6

After Apple added the resize functionality to window borders,
they stopped rendering the size grip in most apps. Hence we do not
need to either.

Since the status bar height depends on the status bar being
there, we considered the safest option to keep it but make
it hidden.
