dotgen make_flat_adj_edges: fix truncation to int during intermediate calculations

Like the prior commits, the problem fixed in this commit seems to have been a
mistake in ebd6191b0eec6e23d96c92aaa06212de339207e3 in not updating these
variables to doubles when transitioning to double-based points. Squashes 4
-Wfloat-conversion warnings.
