Post alt OCR

[timbray]

I use Phanpy for all my Fediverse now, with two exceptions (a) admin/mod work and (b) posting.

(a) isn't Phanpy's problem, masto client is OK.

But when posting I often include screenshots, and I never post an image without alt text, and the native client has the "detect text from picture" feature that makes it easy. So when I need that I switch back to masto client.

(Not a matter of life & death, obviously, but something useful for the roadmap.)
