Sphere refraction filter is now functional.
Chroma key blend now respects alpha channels.
Made significant changes to the internal architecture of two-input filters, which should fix many bugs. You no longer need to set targetToIgnoreForUpdates in almost all cases.

Fixed a leak with resized still images.
