Hmmm... I probably should have done that. However that implementation
seems to be based on a somewhat expired version of dwm, since drw.c and
util.c are not yet present.

As far as the issues I had: Error handling is done in some ways counter
to what the official version does. This implementation reacts fataly for
some errors, namely those it directly requests, but completely ignores
errors in the event queue, i.e. unexpected errors.

Also, the FontSet issue is addressed rather drastically - by excising
the feature completely. Which in the end means the inability to draw
titles that have a more diverse character set than just ISO Latin-1.

Maybe it was. However, I found no such conversation in my personal
archive of this list (which goes back maybe a year or so), and the
official version of the archive has no search function, nor has any
attempt at sending Google on that archive been successful. And since the
archive only has index pages by month, I can't even get the entire
message index, or even the message index per year and search via C-F.

Also, maybe the majority here is unaware of what kind of a code base
Xlib is. I have seen OS kernels with less complexity.
