;;; Grandmother's Ultra Vivid Solarize::
;;; Requires:
;;;
;;; Another quality script brought to you by the Grandmother Coffee House production.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; Notes on Options
;;; 1. Automatic (Ultra)-Vivid gives vivid and highly saturated color solarization
;;; 2. Automatic Vivid gives colorful (purple) solarization
;;; 3. With Automatic turned off, the (Ultra) and Vivid solarization
;;;    needs manual input adjustment via the sliders.
;;; 4. With Automatic turned off, Vivid at 127 is equivalent to
;;;    Normal Solarize (slight difference due to curve smoothing)
;;; 5. With Automatic turned on, (Ultra)-Vivid is close to
;;;    Automatic off, Vivid at 255, except there is richer color enhancement.
