Add monitor "Rotate" option taking one of "normal", "left", "inverted" or "right". However, because initial mode selection is made before the screen is completely initialized, we cannot create the shadow pixmap object at this point. Pend the shadow pixmap creation until the block handler. Note that this code is not completely functional yet.
