Preferences › Devices › Enable Touch Gestures (on by default) was stored but nothing read it: no touch gesture was implemented. - `touch::Taps` follows the fingers egui reports (winit reads them from the system: WM_POINTER on Windows): fingers down together and lifted within half a second, none moved more than 16 points, is a tap. Two fingers undo, three redo, with the preference on. - egui makes the first finger the pointer too, so it has pressed on the canvas by the time a second lands: that press is dropped then (its tool interaction rolled back), and the rest of the gesture presses nothing. The tap so undoes what came before it, not the first finger's mark. - A pen is one contact, so pen strokes and taps are unaffected; pinch zoom is unchanged.
