currently fltkhs is MIT licensed.

http://www.fltk.org says

FLTK is provided under the terms of the GNU Library Public License, Version 2 with exceptions that allow for static linking.

iiuc, end-user apps that statically link can be licensed more permissively (?). but fltkhs bundles the source too.

I'm ok changing it to GPL2 so long as the exceptions for static linking can also be applied to the binding.

So, I found the right way to do this, via FLTK-exception.
