   `filter` (przy kazdej klatce trzeba go nalozyc na nowo), `scale`
   w animacji (wymusza ponowne rasteryzowanie gradientu w nowej skali)
   i `inset: -35%`, czyli warstwa o powierzchni prawie trzech ekranow.
   Blur 0,35 px byl i tak niewidoczny, skala siega najwyzej 1.07 (wiec
   12% zapasu wystarcza), a `will-change` promuje warstwe tak, ze sam
