[Laszlo-dev] How should states _really_ work?

[P T Withington]

As part of fixing LPP-631 in r8032, states now remove constraints that  
they override when applied, and they _restore_ those constraints when  
removed.  This breaks dragging and resizing of the swf debugger window!

The swf debugger starts out with its dimensions defaulted to a  
percentage of the canvas.  Percentage values are constraints.  This is  
nifty, because if you resize your browser window, the debugger window  
nicely resizes too.

But if you try to drag or resize the window, the drag or resize state  
gets applied, the window tracks the mouse, but when you let go of the  
mouse, the state gets removed and the previous percentage constraints  
are reinstalled, snapping the window back to its starting position.

My question:  Is this a bug in states?  Should they _not_ restore  
constraints they removed?  Is this a bug in drag/resize states?   
Should they be overriding the base state behavior of restoring  
constraints?  Or, is this just a bug in the swf debugger?  Should it  
only size to the canvas initially and not respond to canvas changes?   
Or should it be improved to track the canvas until it is resized or  
dragged?
