/* SL / OS camera controls
up / down / w / s moves avatar forward / backward
shifted version does the same
double tap triggers run mode / or fast fly mode
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.
TODO - implement things like space mouse, sixaxis, phone as controller, joysticks, data gloves, etc.
*/
/* 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".
* Where 1.0 means "what ever the standard move is if that key is held down".
* 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.
* Which would even work in fly mode.
* A joystick could be set to range over -2.0 to 2.0, and just set it's part directly.
* A mouse look rotate, well will come to that when we need to. B-)
* Setting the x or y to be the DIFFERENCE in window position of the mouse (-1.0 to 1.0) since the last frame.
*
* TODO - In the Elm_glview version, 2.0 seems to be correct speed for walking, but I thought 1.0 was in Evas_GL.
