More waitbar weirdness

[Rik]

10/4/11

I just pushed some more improvements for waitbar.  However, in the process
I found some more oddities that should be fixed at some point.  First, the
initial call to waitbar produces a patch of a given size.  A second call to
waitbar, to update the fraction of the progress bar, causes the entire
patch object to change size.

Second, the toolbar in the lower left is active and visible.  If you press
the 'A' button for autoscale it opens up a brand new figure window.
