/*
* The following is some guesswork on how the TV encoder flicker
* filter/rescaler works:
*
* It seems to use some sort of resampling filter, it is controlled
* through the registers at NV_PTV_HFILTER and NV_PTV_VFILTER, they
* control the horizontal and vertical stage respectively, there is
* also NV_PTV_HFILTER2 the blob fills identically to NV_PTV_HFILTER,
* but they seem to do nothing. A rough guess might be that they could
* be used to independently control the filtering of each interlaced
* field, but I don't know how they are enabled. The whole filtering
* process seems to be disabled with bits 26:27 of PTV_200, but we
* aren't doing that.
*
* The layout of both register sets is the same:
*
* A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40]
* B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c]
*
* Each coefficient is stored in bits [31],[15:9] in two's complement
* format. They seem to be some kind of weights used in a low-pass
* filter. Both A and B coefficients are applied to the 14 nearest
* samples on each side (Listed from nearest to furthermost. They
* roughly cover 2 framebuffer pixels on each side). They are
* probably multiplied with some more hardwired weights before being
* used: B-coefficients are applied the same on both sides,
* A-coefficients are inverted before being applied to the opposite
* side.
*
* After all the hassle, I got the following formula by empirical
* means...
