Hi All, I'm trying to make the output of my graph-tool drawings a little more pretty. At the moment, if I have two thick edges that intersect at an angle other than 0°, there is some uglyness at the corners; see: http://i.imgur.com/CuEDoth.png and http://i.imgur.com/r54Mp9E.png. It may be worth mentioning that I'm manually setting vertex positions (by specifying `pos` in my graph_draw call). I've mentioned this on the #cairo IRC channel, and they suggest it may be because graph-tool is considering each edge as a seperate line, rather than being part of a larger path - could you confirm that this is the case? It was also suggested that I changing the line caps (presumably to have rounded ends) would solve it - does the API exposed by graph-tool allow this? In cairo, it would be a call to set_line_cap(). Many thanks, Joe
