Updated to the latest Fiona version to fix one bug, maybe caused more.

Pointing the individual projects at the same libraries is getting a bit hackish; this is partly an artifact of compiling across network and local drives. It may be easier to move everything to the network; I haven’t space to keep it all local.

Everything compiles, but now requires a Rift to actually run; I suspect I’ll have a Rift to test on tomorrow.

Also, I’m assuming a square FOV for now.  The Rift’s default is pretty close, but I suspect I’ll need to find a way to force a symmetric viewport (or at least statically sized viewport). That happens somewhere in the code of the 0.4.3 tuscany demo.

Ideally the FOV would be based on the real-world physical size the viewport occupies on the screen.  This is complicated by the Rift choosing a viewport size based on calibration. I’ll test using Oculus SDK defaults until I track down the real numbers.
