NEWT/Pointer Confined: Dispatch mouse move events before enabled; Only request-focus/warp-ptr if enabled

Dispatch mouse move events before enabled
  - Allows user app listener to track to the new centered mouse position
    before using the confined position. This is important for position change usage.
    See simplified demo GearsES2

Only request-focus/warp-ptr if enabled
  - No need to request focus and center mouse if leaving confinement

Demo GearsES2:
  - No need to assume some position changes are erroneous (jumps)
    due to confinement.

  - Track unconfined mouse position, allowing confined navigation
    to have the proper position change value
