SVN commit 648043 by cgilles:

digikam from trunk : Image Editor canvas :

- button from bottom/left corner of editor canvas used to handle pan icon widget, is now a toogle button. it show and hide pan icon view. No need to select a regio to pan to hide pan view. Just press again on the button.

- pan icon view is just more larger (90*60) ==> (120*80). More adapted to large screen.
