DitherTools isn't working well with MT.

Try this script repeatedly and it will crash in dither.dll, when all dither functions are set to either MT=1 or 2
Code:
Dither_convert_8_to_16()
SMDegrain(thsad=200, prefilter=2, lsb_in=true, lsb_out=true)
DitherPost(mode=6)
Prefetch(8)
A solution I found is to set DitherPost to MT mode 3. However, it then causes a severe slowdown when using SMDegrain(prefilter=4) where performance goes from 2.2 to 1.6fps.

Without setting DitherPost to MT mode 3, I can't get rid of the crashes, so it would be nice for someone to investigate.
