LibGfx: Simplify segmentizing paths

Browse source 
Remove SplitLineSegment and replace it with a FloatLine, nobody was
interested in its extra fields anymore. Also, remove the sorting of
the split segments, this really should not have been done here
anyway, and is not required by the rasterizer anymore. Keeping the
segments in stroke order will also make it possible to generate
stroked path geometry (in future).
