* This is not actually a canvas item itself to avoid the dreaded diamond,

|
* 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.

|
|
* A newer, better canvas should remove the need for all the ugly here.
