There are rendering differences given by that patch due to the nature of
working in limited precision; when we extend the trapezoids the inevitable
rounding can cause differences in the edges of the trapezoids.

I think this is unavoidable. I'll try a new version tomorrow tweaked to round
outwards so that we always guarantee to plot at least as many pixels as before,
but it's still not ideal.
