Migrate terminology away from "paper size".

Migrate terminology from "paper size" to "paper format" or "paper
dimensions" as appropriate in documentation and diagnostic messages.
"Format" implies an orientation (which can be overridden in many cases)
whereas size does not.  When only the magnitudes of measurements are at
issue (mainly for internal purposes), use the term "dimensions".
