MMX

A Known issue, with the MMX routines is the lack of full 8 bit precision in the calculations.

Ian fixed that apparently a long time ago (v2.58). See http://avisynth2.cvs.sourceforge.net/viewvc/avisynth2/avisynth/src/filters/focus.cpp?r1=1.11&r2=1.12 . You can remove that comment. Admin 18:42, 21 September 2014 (CEST)

Kernel tech stuff deleted

I removed the following as I think it of interest to developers only.

This is a simple 3x3-kernel blurring filter using the kernel [(1−1/2^amount)/2, 1/2^amount, (1−1/2^amount)/2]. The largest allowable argument for Blur is log2(3) (which is about 1.58), which corresponds to a (1/3, 1/3, 1/3) kernel. A value of 1.0 gets you a (1/4, 1/2, 1/4) kernel.

please feel free to add it back if it is important to the article. --Raffriff42 06:49, 28 January 2016 (CET)
