QPainterPath, toSubpathPolygons/ toFillPolygons/ toFillPolygon deprecations

Because of the deprecation of the QPainterPath methods using a QMatrix as parameter the following application code runs into compiler errors:

const auto ... = path.toSubpathPolygons();

error: no matching function for call to ‘QPainterPath::toSubpathPolygons() const’
note: candidate: ‘QList<QPolygonF> QPainterPath::toSubpathPolygons(const QTransform&) const’

So we have code that does not compile anymore without being guilty of using the deprecated QMatrix.

The expected API would be to have something like:

... toSubpathPolygons( const QTransform& = QTransform() ) const;
