@jheinen, Plots.jl with gr() backend seems to exhibit several bugs on this example.

Bug on `aspect_ratio=:equal`, which is not applied to the z-axes:

```julia
surface(x, y, z', ratio=:equal)

```

Bug on the color scale limits if we set `zlims` to fix the `aspect_ratio` bug above:

```julia
surface(x, y, z', ratio=:equal, zlims=(-2,2))

```
