FONTSAMPLER can show DISPLAYFONT on non display stream (2nd retry)

[MattHeffron]

Enable FONTSAMPLER to display glyphs from .DISPLAYFONT (bitmap font) on non-DISPLAY stream (e.g., PDF)
Change to match 2025-02-03 discussion on Ascent/Descent per-CHARSETINFO vs. whole FONTDESCRIPTOR.
(Use whole FONTDESCRIPTOR.)

Third try at a clean PR.
I checked out master and did a Pull.
I then created this new branch, copied the 2 files into lispusers (replacing the ones there), committed the changes, and created this PR.

This still has a lot of stuff in it that I don't expect to see.

I think your local copy of the master branch has had things merged into it that are making it messy. I'd suggest doing

cd medley
git checkout mth36--FONTSAMPLER-can-show-DISPLAYFONT-on-nonDISPLAY-stream-retry2 # step away from master
cp lispusers/FONTSAMPLER{,.LCOM} /tmp      # save them for safety, check these are the ones you expect
git branch -D master       # delete the local copy of master
get fetch # ensure everything is up-to-date
git checkout master       # get a fresh local copy of master
git checkout -b mth36--FONTSAMPLER-can-show-DISPLAYFONT-on-nonDISPLAY-stream-retry3 # 3rd retry lucky?
cp /tmp/FONTSAMPLER{,.LCOM} lispusers/.
git commit lispusers/FONTSAMPLER{,.LCOM}  # and edit the commit message
git push  # push it back to github
# then open the PR for the new branch in the web interface.

"get fetch" => "git fetch".

Yes! I didn't see all of these commits until the PR was created. Even then, it still shows only 2 files changed. (And the PR is supposed to be comparing vs. the master branch. 🤔

I just did a new clone from github, and I'll create the (next) new branch and copy the 2 changed files there. I'll create the PR from there.

how about adding a HCFILES translation from .DISPLAYFONT to PDF.... so that it would be easy to see what a font was?

Sybalsky had a DANCER font that I've wanted to see, for example.
