There can be a race between the browser receiving window bounds updates
and the IME ensuring the text caret is visible.

* Repeat the text caret visibility request after virtual keyboard
  occluded bounds update. This is a no-op if the caret is already
  visible.
* Fix double-conversion of local bounds to screen bounds in chrome's
  receipt of occluded bounds from ash.
* Clarify variable names with coordinate system.
