Create a new exported global variable, XineramaVisualsEqualPtr. Use this pointer to decide whether two visuals are equal during visual consolidation. This pointer can be wrapped, which allows drivers and extensions to control which visuals are consolidated. A wrapper can reject the visuals without calling down, but must call down and return that result if it deems the visuals equal. This ensures that all layers agree that the visuals are equal. Pass the screen of the other visual into the VisualsEqual callchain. Don't free PanoramiXVisuals since we need it for PanoramiXTranslateVisualID. Don't skip the first visual on the other screen in PanoramiXMaybeAddVisual. Skip the loop in PanoramiXTranslateVisualID if screen is 0.
