That is correct. None of these are used in FLTK. This makes it possible to
compile FLTK on broken compilers and small embedded systems. This does not mean
that you can't use these features in *your* code, if you wish. Eventually.
FLTK 1.3 doesn't even use namespaces.

Yes, we use all kinds of tricks and "old style" coding to keep stuff small and
quick.

You will probably need overloading at some point if you want to draw custom
graphics, but no worries, there are a ton of examples in FLTK and on Greg's
Cheat Sheet. It sounds like you will feel pretty comfortable with FLTK in no
time.
