Includes the addition of an onSetCursor() handler which must be called from both the GAL canvas AND the GAL backend (at least on OSX) to prevent cursor flickering between (for instance) pencil and arrow. Also includes new architecture for point editors which allows them to coordiate cursors with the editing tools (so we can switch to an arrow when over a point).
