 				Creates a new [Projection] that projects positions using a perspective projection with the given Y-axis field of view (in degrees), X:Y aspect ratio, and clipping distances. The projection is adjusted for a head-mounted display with the given distance between eyes and distance to a point that can be focused on.
 				[param eye] creates the projection for the left eye when set to 1, or the right eye when set to 2.
