v4

• Fix the use of an uninitialised variable in Recalculate (kind of important).
• Add some more SAD functions. Block sizes of 8x4, 16x2, 32x16, and 32x32 should now be just as fast as in the original Avisynth plugin.
• Allow YUV422P8 input. The filters only needed to accept such clips, because the required code was already there.

v3

• New filter FlowInter, used by ivtc_txt60mc function.
• FlowBlur: the fractional part of the "blur" parameter is no longer discarded.
• Bilinear resizer used by Mask, FlowBlur, and FlowInter is less dumb.

v2.0

Changes:

• New filters Mask and FlowBlur. They are used by QTGMC.
• New filter Finest. It is used by FlowBlur. It may be of no use to anyone else.
• "dct" parameter is gone once more, because of mysterious crashes in FFTW in Windows.
• More parameters have sanity checks.

v1.1

This version fixes a silly crash and brings back the "dct" parameter to Analyse and Recalculate.
