Probably clearer to say: returns the edges that can be used to resize |panel| by
the user if |panel| is resizable in this strip.

Done.

Can*** makes me think about the bool return value. How about GetResizableEdges
or GetUserResizableEdges?

[Dmitry Titov, 2012/04/13 02:55:45]

GetPanelResizability()?

[jennb, 2012/04/13 19:48:04]

Done. Did not rename CanResizeByMouse() in this patch as I'll be renaming that
in a separate patch to replace ResizeByMouse to ResizeDrag.

 
   // Change panel's bounds and take care of all possible side effects
   // in ths strip as a result of the panel being resized by the user.
