The first four patches are clean ups and helpers to facilitate the implementation of an updated procedure for calculating the partition windows. The entities are iterated first backwards through the pipeline allowing them to request an expanded input window if needed to satisfy their required output. Then, as only the WPF can support clipping on the left edge, (though the UDS can clip on it's right edge) the partition window is then propagated forwards through the entity list allowing them to update any offset which will mark left pixels to be discarded by the WPF. Any expanded pixels to the right edge will automatically be clipped by the WPF as it's partition window will remain fixed.
