* Remove wireframe.
*
* Under -nowirecopyrect, return control to base scheme

* in the new postion or size. Under -wirecopyrect, apply rfbDoCopyRect

*
* -scale doesn't always work under -wirecopyrect, but the wireframe does.
*
* testing of this mode under -threads is incomplete.
*
* returns 1 if it did an animation, 0 if no move/resize triggers
