Great work! Just ran through all the parametric geometry examples and it looks like this corrects the z-axis. Here's the Super Ellipsoid example

Here's another example using this branch:

import pyvista as pv

pseudosphere = pv.ParametricPseudosphere()
pseudosphere.plot(color="tan", smooth_shading=True, show_axes=True)

The master branch forces the major axis to be along the x axis. It's nice to have a uniform convention for all of our parametric and non-parametric geometry.
