- Implemented object edit rotation via dragging, hold ctrl to enable (can drag the corners)
- Changed object edit bar to scale using the center as the origin rather than bottom left
- Changed shape draw options panel to bar that automatically shows during shape draw, similar to the object edit bar
- Removed action to toggle shape draw options panel
Fixed ignored vertices being rotated and sometimes used to calculate object edit bbox
Added simple 'help text' feature, shows at top right during object edit and line/shape drawing (currently, will add more)
