Enable startup-time rotation; change rotation pixmap creation API.

Browse source 
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.
