Re: [Inkscape-devel] NEW: Spiro splines LPE

just tried out the Spiro Splines and I am awestruck, this is completely intuitive and 'self-evident', congratulations and bravo ... question, there is this temporary red spline that appears for a second and then disappears, and bears no relationship to the actual spline, where does it come from? regardless, who said math wasn't fun ?
