Speed up canvas generation?
It can take quite a long time to generate the (potentially thousands) of canvases needed for complete production of large plot sets. Is there any way to speed things up?
- State saving? Challenging to get the comparisons right (in the internal registry) if we try to cache them elsewhere.
- Parallelization of image generation? In principle the various directories could all be processed in parallel. Would take some refactoring however.
