Change the signature of TranslatedFont, and convert it to a proper class

Browse Source 
In preparation for the next patch, this changes the signature of `TranslatedFont` to take an object rather than individual parameters. This also, in my opinion, makes the call-sites easier to read since it essentially provides a small bit of documentation of the arguments.

Finally, since it was necessary to touch `TranslatedFont` anyway it seemed like a good idea to also convert it to a proper `class`.
