Thanks.

Probably not. There is a templine because I first planned on having the
double-line be a little above and below the line that connects the two
handles. However, that turned out cumbersome.
So it's a leftover that I'll remove asap.

I'd rather not touch the renderers, otherwise I would've made the double-line
a style just like dashed and so on. By having most of this code in the line.c
itself, compatibility is guaranteed (well, I think it is) since everything
seems like just having two lines.
