-- These tests depend on loading specific fonts from our test fixtures. Running
-- plain `busted` is sometimes useful (e.g. for IDEs) but will not support this
-- test because fontconfig hasn't been preloaded with the font paths it would
-- need. If that's the case, just skip even defining these tests and call it
-- good. To test a complete set of tests use `make busted`.
