Please could you add an option to render the blob pictures on a white background?

Literally this 🙂

From what I see it's not possible to change background in coot when running in --no-graphics mode.
I'll open an issue in coot, so perhaps it'll get resolved at some point.

As a workaround you can render the same pictures manually:

$ coot --no-guano ./out/blob1-coot.py
