One finger already worked as the mouse. Two or more fingers now make a gesture instead of fighting over the cursor: two drag to pan and pinch to zoom about the fingers, three drag to orbit; a quick two-finger tap opens the context menu, a three-finger tap zooms to the extents and a quick three-finger swipe up shows the isometric view. While a gesture runs the drawing area's own pointer handling keeps out, and the press the first finger started is dropped. Refs #906 Co-Authored-By: Claude Opus 5.5 <[email protected]>
