  Warp pointer into window and simulate keypress using extension.

When the focus argument is a window,  then  device  events
that  would  normally be reported to the focus window or one
of its  inferiors  are  reported  as  usual  and  all  other
keyboard events are reported relative to the focus window.
>>STRATEGY
If extension available:
  Create a window tree and select DeviceKeyPress and DeviceKeyRelease events 
  on all.
  Call xname with focus = window in tree with child (child2, with child
    grandchild).
  Warp pointer into all windows, and root, and simulate keypress/release using
    extension in each.
  Ensure event.xany.window is focus (child2) in all cases except grandchild,
    when it should be grandchild.
  Release any remaining keys.
