This is one of the reasons I was working on moving path-builder to
path2. The other thing I'd like to address in some way is assembling
SBasis that differ by a slight rounding error into a continuous path. In
gear.cpp I nudge one endpoint just slightly. It may also be possible to
nudge both endpoints. Mental is concerned about the numerical issues we
will run into here. Another option would be to add tiny line segments.
I'm concerned that these tiny segments will come back to haunt us with
bug reports when we output svg because it will seem that the nodes
double. I suppose that SBasis to bezier conversion could possibly result
in unexpected segments anyway.

Sometimes path2builder seems completely superfluous. But there are
issues and concepts around it that need to be settled and have best
practices declared.
