text size setting for dictionary lookup

[seebs]

Summary

It'd be nice to have a text size setting.

Reproducing

Open suggestions, paper tape, and dictionary windows. Note how two of them have a font setting.

It will help appreciate this if, due to being an adult human who makes excellent decisions, you have a 10" monitor with 2560x1600 resolution.
