Update GeometryFX sample

1. Move the camera start position inside the model, so that you aren't
just staring at a box when you start up.
2. Turn off the small primitive filter by default, as it costs more than
it saves for this particular model. This does not mean the small
primitive filter is not useful. It just means that this relatively
simple example scene does not have a lot of small primitives.
