Subject: [PATCH] Fix crash on Windows (#2021)

The rusttype backend did not properly support manually specifying font
styles, but instead chose to panic when they are specified.

The rusttype implementation now provides a proper implementation for
handling `bold`, `italic` and `regular` font styles.

This fixes #2020.
