Rendering optimisation, which gives best results for zoomed in drawings with complex (multi-node) paths. Optimisation focus - eliminating cubicTo and LineTo nodes outside of visible area, so no unneeded calculations is needed and less memory is consumed (this avoids crashes which were occurring previously if zooming into a complex drawing)
