Line width and end-cap options for `draw_mesh`.

[bwinton]

Background
I'm porting an animated maze generator from ggez to quicksilver so that I can run it on the web.
It's taken about a day to figure everything out so far, and not everything is quite working yet…

Describe the problem you want to solve
One of the nice things I can do with ggez is draw 4px wide lines with a round end cap as part of a mesh.
It give a much more friendly appearance…

Describe the solution you'd like
Perhaps an extra parameter to the draw_mesh call? I'm not too particular about the API…

Are you interested in contributing?
While I'm interested, I don't think I have the time to help out on this at this time…

Thanks!

I think this will be covered by lyon support, which is on the roadmap in #552.
