I actually decided to just make a text editor, the way I wanted it to work.
So far I have a working editor that has a tabbed interface (important
for small screens, I think) but have not fully implemented the Syntax
highlighting.
I had to reimplement the Fl_Text_Editor widget to be able to allow
syntax highlighting... I hope to finish it soon.
It is already much nicer than Xedit (the X11 text editor), so this is a
feature I can return to later once the rest of the programs have been
reworked.

I have not looked into how to theme FLTK yet, but I suppose I should :D

technosaurus (a Puppy Linux guy) is probably who brought that up.  He
made a version of JWM that uses nanosvg for svg support, though JWM does
have SVG support already... I do like how small nanosvg is.

I found this, and think you might be interested in it.
https://github.com/beranat/flviewer
It allows mupdf/poppler support, and does the basics for an image viewer.

I appreciate all your input on this subject, I know small, efficient
programs are a passion of yours.

I recently cam across a way to use fl_read_image(...) to create a
screenshot.  I found:

https://stackoverflow.com/questions/46596654/fltk-desktop-screenshot-issue

When looking to see if there was a way to use FLTK to grab the entire
screen (for this purpose), and have built a small screenshot tool (26.3
KiB).  The only output is PNG, which seemed reasonable, since FLTK also
uses libpng.  The program is simple, and eventually I would like to add
single window screenshots, or perhaps, resizeable, but I would like to
finish with all the little programs before extending them more fully.
