Cursor input is now only sent if the mouse is actually over a primitive. This solves an inconsistency where sometimes the incoming point would be in local coordinate space and sometimes it would be global. If you want to capture that sort of input, either cover the space with a clear rect, or capture the input.
Add the :direction option to the Dropdown component so can can go either up or down.
Add specs to functions in components and primitives
Add the Toggle component. Thank you to Eric Watson. @wasnotrice
