simple offscreen bitmaps are supported and/or POT textures.
Note: You simply can initialize a PIT texture w/ a zero transfer
and use TexSubImage (sic) to transfer the net-payload.

I thought PATH would do it ?
Have to double check the order of locations we gather
to load the native library - look in NativeLibrary.
Maybe it's time for a JOGL GL full library path / library name property ?
