Subject: Re: Fix for OSX bug
The problem is that our actual client area is realized as a
subview of the "content view" of the window. That's normal so far. The
odd part is that, while our subview starts out filling it parent 100%,
upon resizes it gets changed to something smaller....
Anyway, here is a revised patch which simply enforces the size of
window_view by calling setFrameSize.
