Pitch snapping

[1ec5]

The two-finger tilt gesture should snap to zero degrees if it appears that the user was attempting to untilt the map, and something like seven degrees if the user initiates a tilt gesture but doesn't quite make it past a few degrees. Otherwise, it's very easy to wind up with a slightly tilted map.

I like this idea. Apple also adds a bit of drift to their tilt gesture, both directions, which seems nice.

This should work for minimum and maximum pitch, as I suggested in the dupe’d #11980:

When a user ends the tilt gesture within ~±10-15° of the minimum or maximum pitch, we should snap to the min/max (as we do with the rotation gesture around due north).

We should still implement this UX affordance.
