set View Port
Tells the server how large this participant's tile actually is, so it can pick the simulcast layer that fits instead of sending pixels you scale away.
Applies to their camera only, never their screen share. Call it when the tile is laid out and when it resizes.
Parameters
width
tile width in pixels, not dp.
height
tile height in pixels, not dp.
Throws
when this device is not receiving their camera.
