New issue 1253: offset text not in tex mode https://bitbucket.org/yt_analysis/yt/issues/1253/offset-text-not-in-tex-mode Michael Zingale: The follow script (on some castro data): ``` import yt ds = yt.load("smallplt16623") s = yt.SlicePlot(ds, "z", "density") s.save() ``` produces an image with the axes in 'km' and the offset text rendered as '1e4' instead of as $10^4$.  a related issue is that if you try to use `axes_unit='1e9*cm'`, you get a spurious `(1+z)` factor -- that is meaningless except possibly for cosmology codes, and should probably be suppressed by default.
