• mask on/off - shows image with/without ROIs
• in regular case ROIs are shown by boarder lines only
• on mouse click close to ROI boarder line > control points shows-up/disappears for one ROI at a time
• click and drag handle to change ROI position/size/rotation or see a menu of actions
• bottom to convert ROIs to mask

Q: how many handles per ROI - minimal or in each corner?

Q: how to add ROI to image

1. select ROI type from GUI - draws default ROI - then move and re-shape it (like in ami2 or Chuck's app) - intuitive but needs more clicks

Implementation pattern

• factory for control handles
• factory for ROIs
