Marc Mutz 1d1b60dee4 QStylesheetStyle: 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(a) / b

as opposed to the double result

  double(a) / b

For lack of trying, I do not know of a value where this would change
the resulting 'fillWidth' value, but better be safe than sorry, and
use double instead of qreal arithmetic.

Also, when calculating fillRatio, we were converting values back and
forth between qreal and double. Using double everywhere avoids that.

Found while reviewing integer arithmetic in QProgressBar as part of
the fix for QTBUG-57857.
