[Paraview-developers] Rendering in Paraview using python

[Andy Bauer]

There are quite a few plugins with ParaView and it's probably a bad idea to
automatically load them all. Some of them change the GUI, others require
MPI, etc.

In your plugin.cmake file you can set your plugin to be automatically
loaded by adding in the AUTOLOAD option. See
http://www.paraview.org/Wiki/Plugin_HowTo#Adding_plugins_to_ParaView_source.
