[squeak-dev] Resizing windows inside-out

Hi all,

Really, really surprised I've never noticed this before, but I've seen it now on Squeak 5.2 and Squeak 5.3 trunk.  32-bit and 64-bit. 

You can resize a Morphic system window, using the top resize border bar, far past the bottom border of the window.  MVC behaves somewhat differently, but probably in a way that will shed light on the problem.

It is at its worst (most visible) when preference #fastWindowDragForMorphic is disabled.  When that preference is enabled, one is disallowed from dragging past the bottom border of the window.  But still, the notion that a window has a minimum size seems to be gone...?

How to reproduce: 
Open up a Workspace window.  Drag the top resize bar downward past the bottom border of the window.  Watch what happens.  Try it again with a different setting for preference #fastWindowDragForMorphic.  Try again in an MVC project or a Morphic project.

Doesn't happen on e.g. version 4.4.
