MPLRC environment variable to set rcparams #6884
Description
I'd like to suggest a MPLRC environment variable which could be set to a JSON encoded dict, that would be merged into the rcparams read from the matplotlibrc.
Typical use case would be similar to MPLBACKEND -- temporarily set some rcparams without having to edit the source or the matplotlibrc.

Interesting idea. Do other programs use this sort of thing?

Using environment variables for "simple" configuration of "base libraries" is pretty standard in the Unix world, right? Using JSON not so much (probably because most of them predate JSON) but that sounds better than introducing one new variable per rcparam.

Actually, a better idea would be to either have MPLRC contain the contents of the rcparams file itself, or have it point to a filename that contains the desired rcparams (in which case process substitution can come in handy) -- thus avoiding the need to invent yet another encoding.
