I agree with getting it in now (after testing) and then improving it after it is in the repo.

Btw, the `nbproject/` files were derived from those in the `apps/toys/` directory, for example, [apps/toys/Hello/nbproject/](https://github.com/openjdk/jfx/tree/68db44a2c80f420c967c64bb85988178a3cf6d9c/apps/toys/Hello/nbproject), and similarly are used to build using `ant`. So they aren't really IDE files any longer, even though that's where they originated back in the FX 2 time frame.

A good cleanup effort would be to rewrite them to remove the NetBeans project structure, but that would be a larger effort than just this one manual test program.
