The intent there is that line()/polyline() will take an extra
parameter to control line thicknesses, and perhaps some extra
parameters to control line ends and joins.

Well, if 0.63 happens soon, it won't have this feature, I'm still
fiddling with the fix for RT#29879.

Going from a line segment to a polygon isn't that hard, see:

This doesn't handle joining lines though.
