Summary

It seems to me that the general trend is thatset takes keyword arguments, whileupdate takes a dict. Hence,
one can do something like:

d= {'key1':'val','key2':2}obj.update(d)# orobj.set(**d)# orobj.set(key1='val',key2=2)

However, this is not fully consistent.

Proposed fix

Make this consistent, probably through some deprecation path. Especially, allset methods seems to be OK, but someupdate methods appears to use theset approach, especiallySubplotParams,GridSpec andGridFinder.

Is there a specific reason for this? (I take it that forGridFinder, there is thempl_toolkits-is-not-that-well-maintained issue.)

Then, at leastText only has anupdate and not aset. Inherited.
