   * Delegate implementing the native methods of android.graphics.ColorMatrixColorFilter
   *
   * Through the layoutlib_create tool, the original native methods of ColorMatrixColorFilter have
   * been replaced by calls to methods of the same name in this delegate class.
   *
   * This class behaves like the original native implementation, but in Java, keeping previously
   * native data into its own objects and mapping them to int that are sent back and forth between
   * it and the original ColorMatrixColorFilter class.
   *
   * Because this extends {@link ColorFilter_Delegate}, there's no need to use a
   * {@link DelegateManager}, as all the Shader classes will be added to the manager
   * owned by {@link ColorFilter_Delegate}.
