Turn fontdict & minor into kwonly parameters for set_{x,y}ticklabels.

anntzer · anntzer · commit 6acd1ced31ba · 2020-03-25T16:24:37.000+01:00
This is consistent with the general trend of making "minor" a kwonly
param, and will help in making set_{x,y}ticklabels just a thin wrapper
around Axis.set_ticklabels.
