Improve window dragging on WASM

Window dragging has been considerably improved by replacing the mouse
events by pointer events and placing a pointer lock on WASM canvas, so
that off-browser window events are delivered to us.

Translation of the drag origin has been limited to inside the canvas, so
that a window cannot be dragged so far that it becomes offscreen and is
unreachable.
