  Improve EGL_ANGLE_power_preference on dual-GPU MacBook Pros.
  
  Add the ability to release and reacquire the high-power GPU, and to
  respond to changes in the active GPU. In Chromium, the GPU process can
  not access the WindowServer. An external process must inform ANGLE
  that the active GPU has changed, and that ANGLE should switch its
  internal context to the new GPU.
  
  Incorporates a couple of functions from WebKit, used with permission,
  to effect this GPU switch.
  
  A follow-on change in Chromium which uses these new APIs will make the
  existing dual-GPU tests pass with ANGLE and the passthrough command
  decoder.
  
  Carry forward Chromium's workaround of disabling GPU switching on
  older MacBook Pros to ensure stability.
  
  Document the process of adding new EGL extensions to ANGLE.
