Affects only the plotAsPng function: Some LibRSVG versions cannot cope
with complex CSS selectors, so the resulting PNG is black and white
only. If this attribute is set to 1, the CSS selector complexity will
be reduced.

Betrifft nur die plotAsPng Funktion: Bestimmte LibRSVG Versionen
k&ouml;nnen nicht mit komplexen CSS Selektoren umgehen, und das
Ergebnis ist ein schwarz/wei&szlig; Bild. Falls dieses Attribut auf 1
gesetzt wird, werden die CSS Anweisungen vereinfacht.
