Are you suggesting some sort of "automatically collapse padding when
on a Fitt's edge" feature? Or even better, make the padding clickable
in that kind of situation? That would be easier if centralizing
padding a bit I guess.

Another thing your mail made me realize, by moving padding into
widgets such as Button the padding area could become clickable (I
guess in some of the implementation schemes I mentioned, the
input-only window would probably end up not including padding, but in
others it could). I don't know if padding should be clickable - or
only clickable if it's between the widget and a Fitt's edge?

If adding a nicer, more automatic way for no-window widgets to get
events (as part of dropping GdkWindow), one possible elaboration would
be to be smart about whether events on padding go to widgets, possibly
including a rule that the widget only gets padding events if the
padding is against a Fitt's edge.

These features all seem like elaborations of "padding cleanup" but I
do think a padding cleanup (and having padding generally be part of
clickable widgets, not part of the layout container) would help do a
nice Fitt's law feature.
