* Remove wireframe.
*
* Under -nowirecopyrect, return control to base scheme
* (check_user_input() ...) that will repaint the screen with the window
* in the new postion or size. Under -wirecopyrect, apply rfbDoCopyRect
* or rfbDoCopyRegion: this "pollutes" our framebuffer, but the normal
* polling will quickly repair it. Under happy circumstances, this
* reduces actual XShmGetImage work (i.e. if we correctly predicted how
* the X fb has changed.
*
* -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
* went off.
*
