Both of the above matplotlib ebuilds need the patch https://github.com/tacaswell/matplotlib/commit/3369e3bc24f98f430593a5d15d8e6d6deb14356e to function properly with >pillow-6.2.2. As indicated in the patch PILLOW_VERSION is now deprecated and the __version__ attribute is present for the subject matplotlib versions. Also, pillow is only pulled in with USE=doc. This would seem to be a bit obscure since pillow is needed for saving 'plots' in a variety of formats, i.e. jpeg, tiff, ..., etc. Often USE=doc refers to documentation relative to the subject ebuild. Perhaps a useflag somewhat more descriptive of why pillow is needed/used would be helpful.
We should also note that discussion in https://github.com/matplotlib/matplotlib/issues/16083 explicitly says that pillow is now a hard dependency in matplotlib master branch, meaning it will be required in all cases for matplotlib 3.3 or whatever comes next after 3.2.x.
I should note that the indicated patch also works for pillow-6.2.2.
FWICS 3.2.2 has this fixed already, so I'm just going to make the dep unconditional.
