Turns out that this doesn't have anything to do with radial shades at all.
Rather the logic in fz_paintlinear has been subtly changed, both by
fz_paintquad not always passing the same three vertices to fz_painttriangle as
fz_paintlinear originally did and by changing the additions in the
shade->extend[1] case to subtractions.
