   * This function allows setting both system defined mouse cursors and

   * and set the custom image to 0 and the hot spot to NULL. To set a custom
   * cursor, set the type to <code>PP_MOUSECURSOR_TYPE_CUSTOM</code> and
   * specify your image and hot spot.

   * @param[in] instance A <code>PP_Instance</code> identifying the instance
   * that the mouse cursor will affect.
   *
   * @param[in] type A <code>PP_MouseCursor_Type</code> identifying the type of
   * mouse cursor to show.
   *
   * @param[in] image A <code>PPB_ImageData</code> resource identifying the
   * custom image to set when the type is
   * <code>PP_MOUSECURSOR_TYPE_CUSTOM</code>. The image must be less than 32
   * pixels in each direction and must be of the system's native image format.
   * When you are specifying a predefined cursor, this parameter must be 0.
   *
   * @param[in] hot_spot When setting a custom cursor, this identifies the
   * pixel position within the given image of the "hot spot" of the cursor.
   * When specifying a stock cursor, this parameter is ignored.

   * is invalid, or if the image is too large.
