My understanding is that file formats deal with logic units most of the
time; so if our output is DPI-dependent, that's a bug to be fixed.

If for some reason there is no time to track down the root of the
problem, adding tolerance or "if (!IsDefaultDPI()) return;" snippets can
work around the problem.
