Dirk Hohndel a7d1dbd013 mobile UI: fix font size breakage on Android
The pointSize() of a font can return -1 if the font was originally specificied
with a pixelSize. Work around this by using QFontInfo to calculate the correct
value.

Additionally, don't use the pointSize() of a font when we can instead use the
calculated size.

This fixes the problem with the missing star ratings on Android.
