Remove the use_split_preview and use_result_cache parameters of gimp_applicator_new(), and allow enabling/disabling the cache (through gimp_applicator_set_cache()) and the preview crop (through gimp_applicator_set_preview()) after construction. Move the preview crop node after the result cache, and remove the separate preview cache node. This eliminates an extra cache buffer, reducing the space consumed by filters, and speeds up split preview, since the cached result now includes the output compositing.
