Also, one minor thing I noticed:

In my original patch, the position reporting in the button area is
disabled no matter whether clicked or not.  This was intentional
because I find it quite annoying that the mouse pointer moves slightly
when I click.  I often missed the target when I pressed strongly,
because my finger slipped a millimeter before the click state got
active.

This is a matter of taste, though.
