Remove some deprecated rcParams.

anntzer · anntzer · commit 18b5c87e2318 · 2017-12-18T08:10:54.000-08:00
- axes.color_cycle was deprecated in 1.5 (68f0afb). - legend.isaxes was deprecated in 2.0 (64accfd). - svg.embed_char_paths was deprecated in 1.3.1 (6d660ce). - svg.image_noscale was deprecated in 2.1 (4a05302) but note that the deprecation was broken to start with as it used None as converter (so trying to set `rcParams["svg.image_noscale"]` currently raises `'NoneType' object is not callable`. - text.* and tick.size were deprecated before 1.3.1 (e34a333).
