Strange, i loaded latest version from SqMap, and there was no such method.

Well, i tested another files located in same directory, and they seem
rendered well.
I don't know why this particular glyph not rendered correctly, i can
only suppose that it
was defined with sequence of data, which wrongly parsed by SVGMorph.
Why i think it's not engine? Because engine can't twist point
coordinates of shape, it can only fail to fill shape correctly. And in
this glyph i see twisting coordinates, look like somewhere SVG morph
starts feeding engine with wrong coordinates.
