editor: gestures work on touch — pinch zooms, a moving finger pans

The stage pointerdown bailed out whenever _markup was set, so in the plan
editor no pointer was ever tracked: no pinch, no pan — on a phone the plan
could not be zoomed or moved at all (owner's report). But drawing is
CLICK-based, so the two coexist: a finger that moves pans (and suppresses
the synthesized click so the release feeds no tool), two fingers pinch, a
clean tap still draws. Pointers that start on labels, handles, markers or
buttons stay out — those run their own drags. The tool preview keeps
following the tracked finger.

New smoke: smoke_editor_gestures (pinch in plan mode, pan without drawing,
tap still draws). Inventory: 140 / 51 / 43 / 66.
