Automatically running the build and unit tests after each source change:

npm run watch

Backlog

• Updating related handles while resizing (e.g. resize top left handle of a rect and update the bottom left and top right as it changes)
• measurement calibration tool
• Config object that allows tool appearance to be customized (e.g. line color, text color, handle size, shape, etc)
• automatically disabling tools when the enabled element is disabled
• reconsider the state management api, it is a bit clunky
• add support for pointer events as an input source
• Reference line renderer for first/last/active
• Annotations (e.g. text, arrows, circles)
• Move all API documentation from wiki into markdown in a doc folder
• key press input source - so user can interact with tools via keyboard (e.g. scroll stack image using arrow keys)
