This is a very well known problem (and not limited to Inkscape btw).
It's specifically mentioned in an OpenGL document I read once. There, the solution is to use the OpenGL functions to pass it an entire grid og triangles as several arrays. One is an array of vertices, and the others refer to vertices by indexes into that array. This just passes the problem on to the OpenGl renderer, which presumably deals with it somehow, given the clue about which vertices (and therefore edges) are to be considered the same.
I don't know if anything coparable is available in SVG, though.
Not built-in. Additive blending should come close though, as long as the shapes being blended don't overlap. If they all have opaque fills you could even handle overlapping shapes pretty well with a more complicated filter, but that's starting to get a bit awkward.
