WARNING: here is a small inconsistency with the standard: in the standard, 'display' is not inherited, but in flake it is!

NOTE: though the standard says: "A value of 'display:none' indicates that the given element and <em><strong>its children</strong></em> shall not be rendered directly". Therefore, using setVisible(false) is fully legitimate here (DK 29.11.16).

parsePattern()

QSharedPointer< KoVectorPatternBackground > SvgParser::parsePattern ( const QDomElement & e, const KoShape * __shape )

protected

Parses a pattern element.

Unlike the gradient parsing function, this method is called every time we reference the pattern, not when we define it. Therefore we can already use the coordinate system of the destination.

In Krita shapes X,Y coordinates are baked into the shape global transform, but the pattern should be painted in "user" coordinates. Therefore, we should handle this offset separately.

TODO: Please also note that this offset is different from extraShapeOffset(), because A.inverted() * B != A * B.inverted(). I'm not sure which variant is correct (DK)
