Here's a non-trivial example of fail when df/dz (Julia skew) is included.
\( z \leftarrow x^2-y^2 +2.2ixy \) (close to M-set).

So, sometimes you need the d/dz and sometimes you don't, and we don't yet know when/why/how to choose automatically - maybe until this is worked out better I should make it a configurable option in the user interface?

That would be great.

Interestingly, auto-skew method almost never works for General Quadratic, but you can do it manually to get an unskewed image.
Some new algorithm seems to be required.
