Scrolling delay.

Browse Source 
When object is close to edge of view Valentina begins scrolling scene to ensure
that the object is visible. In many cases this happens to fast for user. As
solution after correction Valentina will wait 80 milliseconds before procedding
next move. This will give users enough time to react. Such delay is called only
if view was scrolled.
