Undefined behavior when dragging map off-screen
Last modified: 2013-04-15 22:42:02 UTC
Most visible at low zoom levels (e.g. 0) when dragging off-screen: 1. When dragging in x or y direction and releasing the mouse when the map disappears, the map slides back. 2. When dragging both in x and y direction and releasing the mouse when the map disappears, the map slides to a different position than it was before. 3. When dragging the map but releasing the mouse before it disappears (and it moves out of the view just by its "momentum"), the map disappears forever.
I've fixed this by removing the bouncing animation which was neither very nice nor working properly. The tile now goes at most half of its size out of the viewport and cannot be moved further.
