Usability: In vector map, Shift+Left click and drag depends on zoom factor
Compiled from sources at revision "9e6812bb Fix scaling issue after loading map with image item."
- Load a vector map containing only a picture on the "Ground" layer.
- Select the "object" layer which is empty.
- Shift+Drag with the left mouse button: the map moves at the same speed as the mouse pointer.
- Now zoom out and try again: the map moves slower than the mouse pointer.
The map should always move at the same speed as the mouse pointer; i.e. if you click on a certain pixel of the map and drag it, this pixel should remain under the mouse pointer.
