Failure to use true italic font variant

Issue type

Engraving bug (incorrect score rendering)

Bug description

Using italics in standard Times New Roman results in a false, synthesized slanted version of Times New Roman, rather than the true italic version, even though the latter is installed by default on Windows, and recognized as such by other Windows applications such as LibreOffice Writer.

This error occurs with many other system fonts (e.g. Bodoni MT), as well as several non-system fonts (e.g. Source Serif), making this issue rather severe as it makes a large number of fonts nigh-unusable for expression text, bar numbers, or alternate-language lyrics. It does not occur with all system fonts -- for example, Gentium Basic gets correct italics.

Steps to reproduce

1. Open an empty MuseScore Score
2. Set the title and subtitle to font Times New Roman, and the subtitle to italic, in the Properties panel.
3. Observe that the subtitle does not look like Times New Roman italics

Additional context

I'd categorize incorrect text font rendering as an engraving bug; apologies if this isn't true here.
