Still untested, but here's review round 2 :D. Mostly just smaller stuff now, and there's less than it looks at first glance.
I would like for @mootw @TesteurManiak or @ibrierley to also review this PR, and any other community reviews also appricated! It's quite a big PR, so want to make sure I/we haven't missed anything.
Removed this method because it was only used in MapInteractiveViewer.updateGestures and could cause confusion between multi point touchscreen and mutli point trackpad gestures.

One bug with cursor keyboard rotation. Rotation is not tracking the cursor properly. I remember having a similar issue when implementing the algorithm initially. Maybe double checking that nothing in the implementaiton itself has changed, and every variable is being changed/reset at the correct points.
-
Cursor keyboard rotation also no longer sets rotation to the angle of cursor immediately when clicking.

- One bug with fling event end/finished event not being emmitted (when fling is cancelled with tap (as shown in video), or when finished naturally)

- Double tap zoom no longer emits correct event.

- Can no longer fling if drag gesture is disabled. On master, enabling fling without drag would start a fling if the normal conditions were met, but wouldn't drag/move if not, and wouldn't move whilst normal dragging.
- Double tap + drag gesture now loads tiles whilst zooming. master behaviour isn't correct either. The correct behaviour is that new tiles shouldn't load and old ones shouldn't be pruned whilst moving, and the refresh should occur when the gesture completes.
- On tap events and callbacks are no longer triggered.
- Can't seem to perform the new trackpad zoom gesture. Can you explain how to do it?
Still untested on any touch devices. Will perform that testing later.
