Applied my "patch" which refactors the complete codebase to have IEffect support, this is an interface which can be used to supply effects to a bitmap. These effects can now be passed to the OutputSettings (which now is called SurfaceOutputSettings) to control how the output is modified. This is very useful for e.g. OCR which needs a grayscale & resized image.
