hi. i was trying to figure out which font st(1) was using in some
configuration i was running it in.
i created the following (INCOMPLETE!!) patch to print out messages when
what the user requested and what is ended up being used are different.
for example, with the patch
----
st fc4* ❯ ./st -f adflkjdsf
font mismatch: instead of family "adflkjdsf"; we got family "Noto Sans"
font mismatch: instead of family "adflkjdsf"; we got family "Noto Sans"
font mismatch: instead of family "adflkjdsf"; we got family "Noto Sans"
font mismatch: instead of family "adflkjdsf"; we got family "Noto Sans"
----
the incompleteness is, at least partially, from these issues:
- should it always check? #ifdef? command line option?
- what fields should it look at?
- currently it looks at "familiy", "style", and "size". there are
many others
- possibly, one can look at the user's pattern and use some FcP...()
routine to extract *all* the fields the user specified, and look at
those
- when during the start up should it be called? (maybe there's
somewhere where it won't report the same information four times, for
example.)
- *how* should it present any discrepancies it finds to the user?
- right now, it does `fprintf(stderr...)`. that isn't likely of much
help, especially if launched from a window manager (where stderr
probably doesn't get shown to the user, sadly)
- and, obviously, is this even useful.
cheers, Greg

config.h: delete file polluting this branch
i really messed up, back in c0c621a757232df438b536d1c9695b828a0efe8b
or 5d5227df18084aff0b35e9a839a0fd9b71313567.
probably i created the `fontcheck` branch from `mine`, rather than
`master` (not sure if git can tell me that).

Use nord-theme
*"Inspired by the beauty of the arctic, the colors reflect the cold, yet
harmonious world of ice and the colorfulness of the Aurora Borealis."* -
[Nord Theme](https://www.nordtheme.com/)
The default behaviour of st is to reverse the fore- and background
colors of each selected cell. If you don't want the selection-colors to
be reveresed but instead have fixed fore- and background colors apply on
top of this patch the [selectioncolors](../selectioncolors/)-patch. Then
set the following settings in your config.h:
unsigned int selectionbg = 0;
unsigned int selectionfg = 256;
