@jourdain Please review

Note that I had to update the input for the mappers (in my script) on the second render, otherwise I was seeing a crash at the second render: https://gitlab.kitware.com/danlipsa/quickview_optimize/-/commit/b3cc77daf462693b27a25b7daf8bbd79891aba57

I see a similar crash in Quickview, and it seems we don't do that there - but maybe I don't follow the code.
To get that crash in Quickview:

1. Load the 120 dataset (simulation + connectivity)
2. Choose BURDEN1 and CLDLOW. Load 2 variables
3. Lat/lon cropping. Move the left slider to some value, than move it back to 0.

Seems there is an additional issue going on. I still get the crash if I update only the "trim". If I update both the trim and projection I don't get the crash (in my script).

This is fixed.

@jourdain Please review. This fixes all issues I've been able to find in quickview.

LGTM, should I merge?

@jourdain Two more commits. First one didn't reproduced it, but I think it better than before. The second one - a DeepCopy that was bothering me so I debugged to see what was the cause.

I think now it is ready to be merged. You want to take another quick look?
