UITouch coordinates are floating point on iOS, for example for the Apple
Pencil. Is there a way to map this? Seems like this would be easy to implement
based on the QPoint version…
// pks: apple pencil
QPointF QGraphicsView::mapToScene(const QPointF &point) const
{
Q_D(const QGraphicsView);
QPointF p = point;
p.rx() += d->horizontalScroll();
p.ry() += d->verticalScroll();
return d->identityMatrix ? p : d->matrix.inverted().map(p);
}
