FreeImage wrapper in the works

I've got a FreeImage wrapper in the works for doing graphics work in RB outside of the builtin capabilities. In fact, it's almost ready for more widespread testing -- there are just a few things I'd like to complete first before going ahead with releasing it.

That and I'm not sure what I'll do with it. Depending on what the license permits and whether Bill sees any interest in it, it may become a "plugin" available on RBLibrary. Or maybe I'll just give it away libre style.
