Visual font looping setup

[Jean Louis]

I think we should make a function to visually loop through all the
fonts for default Emacs settings. Beyond DejaVu Sans Mono I do not
know which font to use that it looks equally good. This one is very
readable.

What fonts are you using?

I think of a function that first slurps all the font list and then by
using keys it can show the font name and also quickly change the
settings.
