File include/libyuv/planar_functions.h (right):

https://codereview.chromium.org/1479593002/diff/1/include/libyuv/planar_funct...
include/libyuv/planar_functions.h:404: // Interpolate 2 planes by specified
amount (0 to 255).
I'd mention that this interpolation has the same meaning as in ArgbInterpolate
(0 means 100% src0, 255 means 99% src1, etc).

For readers that are looking at just InterpolatePlane without noticing
ArgbInterpolate above.

added version bump.
remove bpp version of function and have ARGBInterpolate call InterpolatePlane
with width * 4.
