I was just able to write a barebones function that causes Pango
to try and load a font, based on the description (string) given;
i.e., what's provided to the "uifont" argument.  It then returns
the description of the _actual_ font that was loaded.

So for example, if I do "tuxpaint --uifont bookman", Pango finds
"URW Bookman", and I see this on STDOUT:

  Requested UI font described by "bookman"
  Actual UI font will be "URW Bookman"

I need to get to bed, but hopefully tomorrow I can work on

This already happens for me.

Note that focus needs to leave the field.  This is also true with the
type-in values in the Joystick tab.

I agree that we probably want it to act differently (make "Apply" (and
"Reset") activate upon _modifying_ a field, since that's the friendliest.
We should do that with those Joystick fields as well.

A quick Google seems to indicate that FL_WHEN_CHANGED, vs FL_WHEN_RELEASE,
is what's wanted... somewhere.  I'm still a newbie with FLTK.

Hopefully I can duplicate the code I'll add to TP, to make this
possible within TPC.  (It will mean that it suddenly depends
on Pango library.  But since TP depends on SDL2_Pango, which in
turn depends on Pango, this shouldn't be the end of the world,
I hope!)

Then it sounds like it's possible by changing from an Fl_Input
to an Fl_Input_Choice widget.
