FlyControls

Fly navigation similar to the fly modes of DCC tools such as Blender, matching EASEL.js r186. The object moves and rotates freely in its own local frame, with no target or limits. Keys: W/S move forward and back, A/D strafe, R/F move up and down, the up/down arrows pitch, the left/right arrows yaw, and Q/E roll. Key presses with Alt held are ignored. The pointer position relative to the element center yaws and pitches the object; with dragToLook this applies only while a pointer is pressed, otherwise the primary button moves forward and the secondary button moves back. Dispatches change from update(delta) when the object moved or turned.
