* A compose_rotations boolean field has been added to the type Camera;
now camera rotations can meaningfully be used in an environment with
gravity (fixed axes) or in a 0-gravity one (free axes).
* A bug in the video capture has been fixed: frames of any width are
now captured correctly.
* The demo now includes a nice Airbus A319 model
