Where is the `by-backend' function defined?

What'd be nice is that you could say (in a *file* property) that the
extension for LaTeX always has to be .tikz, for HTML .svg and .png in
all the other cases.

Then, you could simply give the base name of the figure where
appropriate, in a "DRY" configuration.
