ridePosefunction

The camera of a body-borne view: at position, looking at the Earth, with the way the body is going at the top of the picture. look: "horizon" tips it forward until the horizon is a little above the middle. A drag looks about from there, as a head on a pivot does: yaw turns the camera to its left and tilt tips it towards the bottom of its picture, so the ground follows the pointer (right for a drag right, up for a drag up); the angle for each pixel of the drag is the field of view's, so the pace is the same at any zoom. zoom narrows the field of view.
