[chlor-develop] GrabHandTool and autoscrolling

[<chl...@li...>]

Hi group,

just updated the GrabHandTool to make it behave a bit better.  
However, when moving outside the drawing area, autoscroll routine of  
ChlorMainView kicks in and results into a "bumpy" appearance.

Try also to move the window around a bit, when the GrabHandTool is  
active - the behavior is also a bit strange.

Anyhow, I'm guessing that it would help if we could turn off  
autoscrolling when the GrabHandTool is active. However, I neither  
want to make ChlorMainView aware of the active tool, nor make it  
stateful - any better proposals?

Kind regards,
	Florian
