For emitter particle systems, these were never rendered anyways, Path is
kept for hair systems of course.
As a consequence, the new default for particle systems is:
- render as None (users have to explicitly set this to object/
collection)
- display as point
When changing to Hair type, this automatically gets set back to
- render as Path
- display as Render
Changing back to emitter, will use points as display again (and render
as None -- same here, users have to explicitly set this to object/
collection)
Not sure if this is still for 3.6, patch is for 4.0 for now.
