It's a bit unfortunate that fonts need to know about the renderer, but type 3 fonts contain PDF drawing operators, so it's necessary. On the bright side, it makes it possible to pass fewer parameters around and compute things locally as needed. (As we implement more fonts, we'll probably want to create some functions to do these computations in a central place, eventually.) No behavior change.
