fturn.

What

Fast implementation of TurnLeft(), TurnRight() and Turn180() AviSynth functions.

How

FTurnLeft(chroma=true, mt=true)
FTurnRight(chroma=true, mt=true)
FTurn180(chroma=true)

Why

Great performance improvements for antialiasing scripts like maa. You can disable chroma processing in case you don't need it (almost often in antialiasing scripts).

Requirements

SSE2 is required. The plugin is also optimized for SSSE3 so you can assume slightly better performance if your CPU has it.
