Allow smooth curve stroking for very wide lines
The earlier limit set on the curve threshold turned out to be too
strict, leading to visibly bad rendering in reasonable use cases.
Ref. 5322998a0ba80b1e095340245ddb00aaf5947be9
As a drive-by, add a missing fixed-to-real conversion. (This is a
no-op in a default build, where qfixed==qreal.)
Fixes: QTBUG-85193
