/* SL / OS camera controls
    up / down / w / s		moves avatar forward / backward

	    Running backwards turns your avatar to suit, walking does not.
    left / right / a / d	rotates avatar left / right, strafes in mouselook
	shifted version turns the avatar to walk sideways, so not really a strafe.
	So not sure if the "strafe" in mouse look turns the avatar as well?
    PgDn / c			crouch while it is held down	move up in flight mode
    PgUp			jump				move down in flight mode
    Home			toggle flying
    End				Nothing?
    Esc				return to third person view
    m				toggle mouse look
    mouse wheel			move view closer / further away from current focused object or avatar
    Alt left click		focus on some other object
    Ins				???
    Del				???
    BS				???
    Tab				???

    Mouse look is just first person view, moving mouse looks left / right / up / down.
	Not sure if the avatar rotates with left / right, but that's likely.

    mouse moves With the left mouse button held down -
				left / right		up / down
				---------------------------------
    for avatar			swings avatar around	zoom in and out of avatar
    for object			nothing
    alt				orbit left / right	zoom in and out
    alt ctrl			orbit left / right	orbit up / down
    alt shift			orbit left / right	zoom in and out
    alt ctrl shift		shift view left / right / up / down
    ctrl			Nothing?
    shift			Nothing?
    ctrl shift			Nothing?

    Need to also consider when looking at a moving object / avatar.

    I think there are other letter keys that duplicate arrow keys and such.  I'll look for them later, but I don't use them.
    No idea what the function keys are mapped to, but think it's various non camera stuff.
    I'm damn well leaving the Win/Command and Menu keys for the OS / window manager.  lol
    Keypad keys?  Not interested, I don't have them.
    Print Screen / SysRq, Pause / Break, other oddball keys, also not interested.
    NOTE - gonna have an easily programmable "bind key to command" thingy, like E17s, so that can deal with other keys.
	Should even let them be saveable so people can swap them with other people easily.

/* A moveRotate array of floats.
 * X, Y, Z, and whatever the usual letters are for rotations.  lol
 * Each one means "move or rotate this much in this direction".

 * So a keyboard move would just change it's part to 1.0 or -1.0 on key down,
 *   and back to 0.0 on key up.  Or 2.0 / -2.0 if in run mode.

 * A joystick could be set to range over -2.0 to 2.0, and just set it's part directly.
