It's just that we put the pieces together differently. Canvases use a
vector-graphics conceptual model and not a raster-graphics model. This
means that you have to put a raster plane on the canvas (e.g. a window
or, more usefully here, a photo image) and draw on that.

Doing it this way makes some things easier, and others more difficult.
Myself, I like having the widget know about the things I'm drawing on
it, since that lets me do fancy features ("hypergraphics") more easily.
