The unaligned size is not handled in setctx_2d(), causing edges of images
to have improper segmentation prediction, which causes visual artifacts
at image edges a few frames later.
this quiets a warning:

This is required if it's subsequently re-enabled with no value updates
(which means, use values that were previously set).

See sample vp90-2-14-resize-fp-tiles-16-8-4-2-1.webm from the vp9 test
vector set which reproduces the issue. This probably costs a few cycles,
but I don't think there's an easy way to workaround that.

The minimum of the ath(x, ATH_ADD) function depends on ATH_ADD.
This patch uses the first order approximation to determine it.
For ATH_ADD = 4 this results in the value at 3407.06812 (-5.24241638)
not the one at 3410 (-5.24237967).

Patch to support VP9 encoding with new profiles 1-3.
Profile 1 (8-bit 422/444) should work with default libvpx
configuration.
However you will need to configure libvpx with
--enable-vp9-highbitdepth before building and linking
with ffmpeg for profile 2 (10-/12-bit 420) and profile 3
(10-/12-bit 422/444) encoding.
You may use the appropriate profile option on the
command line:
-profile:v 1 for 422/444 8-bit encoding
-profile:v 2 for 420 10-/12- bit encoding
-profile:v 3 for 422/444 10-/12-bit encoding
If you do not use the -profile:v option, it will be deduced
from the source format.
