This allows making the master screen's pixmap_dirty_list entries explicitly reflect that we're now tracking the root window instead of the screen pixmap, in order to allow Present page flipping on master outputs while there are active slave outputs. Define HAS_DIRTYTRACKING_DRAWABLE_SRC for drivers to check, but leave HAS_DIRTYTRACKING_ROTATION defined as well to make things slightly easier for drivers.
