As an aside to the scheme issue, I just found that if I add in a
Fl::get_system_colors();
(I put it after the make_current())
and then added the following to .Xdefaults:
dillo*background: red dillo*foreground: yellow
Then dillo's dialogs, and certain parts of the UI, and -- interestingly -- the default text color on pages, well, it all turns rather red&yellow in general.
The src talks about KDE, at least, setting those values in xrdb.
If it should happen that many of the various desktop environments set these values, getting this all to work reasonably correctly might be pleasing to everyone nowadays who expects all of their windows to look similar. People are very first-impression ("It's ugly!" *deletes*)...
For that matter, I will say that all of the grey in fltk by default is not very nice.
