LibGfx: Add ScaledFont::scaled_with_size()

Browse source 
It's like ScaledFont::with_size(), except that it guarantees that the
result is non-null and ScaledFont. (Smart pointers don't allow
covariant return types, else we could just narrow down the return
type of with_size() while still overriding the base method.)

No behavior change.
