Log message:

Add SmartFlt-based resample function. it could probably do with a few optimizations.
set r_smartflt to 1 to enable, and use the r_smartflt_y, r_smartflt_cb, and r_smartflt_cr cvars
to set the thresholds for the three channels. changes only take effect on the next texture upload.

Y is essentially brightness, Cb is the blue color, and Cr is the red color. the C* channels change
values faster than the Y channel. (also, Y is mostly green.)
it would be nice to be able to use this for some other textures, too. :)
