//! Applies a blur, tint color, and saturation adjustment to @a inputImage, |
//! optionally within the area specified by @a maskImage. |

//! @param inputImage |
//! The source image. A modified copy of this image will be returned. |
//! @param blurRadius |
//! The radius of the blur in points. |
//! @param tintColor |
//! An optional UIColor object that is uniformly blended with the |
//! result of the blur and saturation operations. The alpha channel |
//! of this color determines how strong the tint is. |
//! @param saturationDeltaFactor |
//! A value of 1.0 produces no change in the resulting image. Values |
//! less than 1.0 will desaturation the resulting image while values |
//! greater than 1.0 will have the opposite effect. |
//! @param maskImage |
//! If specified, @a inputImage is only modified in the area(s) defined |
//! by this mask. This must be an image mask or it must meet the |
//! requirements of the mask parameter of CGContextClipToMask. |
