Push CompositorFilterOperations creation out of GraphicsLayer
Push knowledge of FilterOperations out of GraphicsLayer and into
PaintLayer. This eliminates one dependency from platform/ code to the
FilterOperations structure. The motivation is to try and make
FilterOperation(s) a core (style) type, to make interaction with the
style system and other parts of core easier. It will also aid in
enabling a more layered structure on the various filter-related data
structures.
Also change the various generator functions to return a
CompositorFilterOperations by-value rather than through a out-variable.
