this specific use is going away via #16171.

`MathTextParser("bitmap")` is rather low-level APIs to convert text
strings to images. Instead, one can use a much more generic method,
namely directly drawing to a new Figure() and saving with
`bbox_inches="tight"`. Alternatively, if one really wants a single
function call, there's still `mathtext.math_to_image`.
Also fix the wx example to use light text colors when so directed by the
system theme.

Why not use math_to_image here?

Why not use math_to_image in both of the examples?
|
Because it's a super-specialized API which I don't think is particularly interesting to demonstrate (or even to expose), whereas drawing on a figure and saving with tight bbox works for basically anything you may want to draw -- including text, but not only that! |
