[Inkscape-devel] Which container used for path nodes?

I'm not sure where in the source tree to look for this, so I'll ask this here.

What container does Inkscape use to store the nodes of its paths? I mean, a drawing program would often use (in STL terminology) push_back, pop_back, insert and erase. (I don't think push_front would often be needed.) The contained value type would probably contain a few flags in addition to the x,y coordinates. So I'm curious what container you people chose to cater to these requirements.

Thanks.
