/* Chromatic Aberration Fixer (original: http://pastebin.com/wEAp3tuM) rx/ry adjust how much to resize the red plane; bx/by is the same, but for blue. warp adjusts warpsharp strength on red/blue planes. clamp sets whether the chroma (after converting back to yv12) should be limited by the original chroma; this prevents introducing chromatic aberration on, for example, hardsubbed text without chromatic aberration.
