If you feed a "polylines" through a Color with opacity < 1.0, dxexec
core dumps at libdx/volume.c:550 (see attached).
Switch Color's opacity to 1.0, and it works. Also, if a "lines"
dataset is substituted for "polylines", it works.
I haven't picked through it, but it looks a little suspicious that
tile.c::patch() thinks polylines are "regular" (vs. "irregular"). Maybe
that's it (?)
