Change the current thumbnail/mini map behavior.

Current :
To deplace the viewport, you can use the minimap in the following way :
“drag the view box in the area that you want to display”

Wanted :
A simple "click" on the new targeted view is simplier.

Hello,

Thanks for your PR.
However, it solves half of the problem (my bad, the issue was unclear).

In addition to change the view when clicking on a new area in the minimap, would it be possible to browse into the minimap ?
Sometime, the zoom level is high and the minimap doesn't show the other part of the image so it will be needed to proceed of a little browsing before clicking on the right spot.

Can you see if it is possible ?
