Pinch-to-Zoom is incompatible with two-finger gestures

It doesn't work any better here, than on Google Maps: Assigning both rotation & zoom to two-finger gestures, results in pinch actions going undetected due to two-finger-swipe action being detected first. A separate Zoom control (or zone) is needed on mobile, instead of pinch-to-zoom. Note that this is not limited to one device or OS; pinch-to-zoom is unreliable when other two-finger gestures are active, across all touchscreen interfaces.
