Allow event callbacks on Canvas component

[sami616]

Similar to a mesh, it would be great to have event callback props for things like onPointerMove, onWheel etc on the canvas element.

Ive tried a few and none seem to fire, have I misunderstood? Or have they been omitted for a reason?

you can put them on a wrapper div around canvas. it just doesn't spread all props, only a few.
