+`EngFormatter` now accepts `usetex`, `useMathText` as keyword only arguments
+``````````````````````````````````````````````````````````````````````````````````````````````
+
+A public API has been added to `EngFormatter` control how the numbers in the ticklabels will be rendered.
+By default, `useMathText` evaluates to `rcParams['axes.formatter.use_mathtext']` and
+`usetex` evaluates to `rcParams['text.usetex']`.
+
+If either is `True` then  the numbers will be encapsulated by `$` signs. When using `TeX` this implies
+that the numbers will be shown in TeX's math font. When using mathtext, the `$` signs around numbers will
+ensure unicode rendering (as implied by mathtext). This will make sure that the minus signs in the ticks
+are rendered as the unicode-minus (U+2212) when using mathtext (without relying on the `fix_minus` method).
