Motivation

I want to use the Canvas tiles. preferCanvas sounds like it should use canvas where possible.

Suggested solution

It may be that preferCanvas can also implement L.TileLayer.Canvas?

Alternatives considered

I saw #4844 / #6879 but I think they are requesting only 1 <canvas> for all the tiles, which I think is more complicated implementation.
