Emilio Cobos Álvarez bdca8af91d Bug 1655558 - Retrieve the paper margins lazily on Windows. r=jwatt,bobowen
This is no worse than what we were doing.

In the future, instead of just querying the margin we may want to query
extra information that requires a DC in windows too or what not, for
example.
