Original change's description:
> GrTessellator: fix for ping-pong split fuzzer hang.
> 
> Change 3b5a3fa8b1c11d4bd4499b040311f4c3553ebf8c introduced support for
> splitting on out-of-range intersections. However, this is only necessary
> for correctness when the edge is nearly-flat (the top and bottom
> points only differ by 1/2 machine epsilon in the primary sort criterion).
> In other cases, it can cause repeated splitting and re-merging of edges,
> as the intersection code (being approximate and not exact) may produce a
> ping-pong set of intersections.
> 
> The fix is to support out-of-range intersections only if they differ by
> 1/2 machine epsilon. This also generalizes the
> out_of_range_and_collinear() check, so it was removed.
