Canvas
The Canvas
widget invokes a function each time it needs to paint.
This function has access to a graphics context exposing most of
Kludine's 2D graphics API.
A Tick
can be attached to the Canvas
to have a callback invoked at a
steady rate. This tick function can be used to update the state of the Canvas
,
and it can signal when the Canvas
should be redrawn.
