NEWT Reparent/Fullscreen: Fixes X11 unsuccessful return to parent window; Add reparentWindow(..) top-level position arguments; Misc

- Fixes X11 unsuccessful return to parent window
  On X11 when returning to parent window (-> CHILD),
  we have to set the window invisible and wait for the result.
  Otherwise it sometimes happens that the WM's reparent operation fails,
  i.e. the window won't become a child of desired parent and is positioned randomly.

- Add reparentWindow(..) top-level position arguments
  .. allows bringing the child-window to top-level w/ a desired position.
  Otherwise the window would be positioned elsewhere as a top-level
  as the plain reparenting operation.

  X11 needs to set position and size _after_ making the window visible,
  otherwise WM may ignore the XConfigureWindow request.

- Reparent recreate shall always store the desired position and size
  On OSX/CALayer when recreation is being used, we need to store the pos/size
  for later creation.

- Tests: Use 'NewtAWTReparentingKeyAdapter' where possible (reparent/fullscreen)
  instead of duplicating such code.

  NewtAWTReparentingKeyAdapter: Performs reparenting and fullscreen operations
  off-thread (i.e. not on AWT/NEW EDT) while decorating the action w/
  revoking/restoring the ExclusiveContextThread (ECT).

Manually tested 'TestGearsES2NewtCanvasAWT' reparenting and fullscreen
on X11, Windows and OSX/CALayer w/ JDK 7u40 successful.
