Detailed Description

Base class for canvas notes (sustained note rectangles, percussive hit diamonds, and velocity lollipops)

This is not actually a canvas item itself to avoid the dreaded diamond inheritance pattern, since various types of canvas items (Note (rect), Hit (diamond), etc) need to share this functionality but can't share an ancestor.

Note: Because of this, derived classes need to manually bounce events to on_event, it won't happen automatically.
