Improved window resizing responsiveness.

Browse Source 
The reformat code was being run on every resize event,
which chokes on most resizes which end up emitting a lot
of resize events.  Now it waits and processes a bunch of
resize events until there aren't any left, and only does
the actual reformat on the last one.
