Description

When moving or rotating ways or multiselections, iD currently relies on the position of the hovered mouse cursor. This makes these operations impossible on touchscreens where pointers cannot hover—dragged touches simply pan the map.

We should look into a workflow where the mapper can grab the feature and drag it around instead of it following the cursor immediately. See also #3372 for talk of a "transform tool"…

Contributor guide

Research direction
Investigate how iD handles mouse events for move/rotate operations and implement equivalent touch event handling with drag gestures. Refer to touch event APIs and existing drag implementations in the codebase.
