QFusionStyle: don't lose precision when drawing a progress bar
When qreal is float, it cannot represent all values an int can take,
so we may lose precision in the expression
qreal(value) - minimum
as opposed to the exact result
qint64(value) - minimum'
For lack of trying, I do not know of a value where this would change
the resulting 'progressBarWidth' value, but better be safe than sorry,
and use the 64-bit integer expression instead of floating-point.
Found while reviewing integer arithmetic in QProgressBar as part of
the fix for QTBUG-57857.
