-/**
- * @brief NinePatchMaskEffect is used to control which parts of an image are visible, using the alpha channel of a separate mask image.
- *
- * The mask image is expected to be smaller than the main image being viewed.
- * Conceptually the mask image is divided into a 3x3 grid (9 patches). The middle patch is stretched whilst the outer border is not.
- *
- * Usage example:
- *
- * @code
- * ImageActor actor = ImageActor::New( Image( EXAMPLE_IMAGE_PATH ) );
- * NinePatchMaskEffect::Apply( actor, MASK_IMAGE_PATH );
- * @endcode
- *
- * NinePatchMaskEffect is mutually exclusive with ImageActor::STYLE_NINE_PATCH i.e. the actor's main image should not be a nine-patch.
