It would be nice if you mentioned DomTerm. You can use the following text as you find suitable

DomTerm's image support appeared in 2016.

Does not use a specific image protocol, but has an "insert HTML" protocol. The typical way to insert an image is to insert an HTML <img> element, with the src attribute using a data: URL scheme, with the actual data inline as base64. Any image format supported by the underlying browser engine (typicall png, gif, or jpeg) is allowed.

The <img> element can contain attributes such as width, height,alt and options to add scrollbars. The domterm image command-line command provides options for setting many of these.

The resulting image is treated as an extra-large cell. (DomTerm supports variable-width fonts and "cells, as well as variable-height rows.)

SVG images and Sixel are also supported.

Hey @PerBothner. Many thanks for participating! Of course i can and will add DomTerm's image support to the prior art section. I just didn't take too much time to look into the web tech terminals - i should have done that.

FYI: I've taken a slightly modified subset of your text proposal above. This draft spec only cares about actual prior art protocols, not terminals per-se, so it won't mention any other already mentioned image protocol (such as Sixel) or what CLI tool is provided.

p.s.: I've also accidentally pushed into the preview branch, which automatically creates a prerelease. I decided to keep that, so we all have an up-to-date PDF/md snapshot for those who do not prefer reading LaTeX sources. :-)
