   V9 – SİNEMATİK YAVAŞ UZAKLAŞMA (masaüstü + mobil)
   Eskiden görsel 1.04x sabit zoomla duruyordu. Şimdi hafif yakından
   başlar, slayt süresince yavaşça geri çekilir ve neredeyse tam kadraja oturur.
   Fare paralaksı (transform) aynen çalışır; zoom ayrı "scale" özelliğiyle yapılır.
     --kb-start : açılıştaki yakınlık   (1 = zoom yok)
     --kb-end   : kapanıştaki yakınlık
     --kb-ease  : geri çekilme eğrisi
   Masaüstü: kapanış 1.02 (paralaks kenar boşluğu bırakmasın diye).
   Mobil: paralaks yok, kapanış 1.00 = görsel kırpılmadan (cover'ın izin verdiği kadar) görünür.
   ========================================================= */
