M9.11: Blur & Sharpen and Distort effects (CC Radial Blur, Camera-Shake Deblur, CC Flo Motion, Liquify, Rolling Shutter Repair)

Liquify stores its strokes as effect data and replays them into a cached
displacement mesh; liquify.stroke / liquify.clear commands for agents.
Rolling Shutter Repair measures motion with effectcraft-track KLT (new
effects -> track same-layer edge).
