Don't use small path renderer with high distortion transforms.

The dFdx, dFdy functions appear to become less accurate as the
distortion in a given transform increases. We could possibly counteract
this by passing in the inverse of the transform, but this is taking the
small path renderer well past its original intended use, which is for
rendering small paths, and icons in particular, with similarity
transformations.
