vorbis warnings from ronny chevalier
...
I manually made these changes because they
disabled some substantial amounts of code,
and I wanted to make sure this wasn't due to
original code having bugs or deviating from
the specification

My guess is people who care about premultiply also care about color space.

Do the multiply inline, it should be a tad faster and not corrupt our data.

Specify a channel as having premultiplied alpha and use it to un-premultiply all other channels before resampling.

When doing a perfect po2 nearest neighbor downsample don't allow -0.5 and 0.5 to both contribute to a texel or you'll get a double tap.

Add a test suite to do a bunch of different resizes to find problems. One problem found was an incorrect calculation of texel support how many margin texels needed when downsampling. When downsampling we need to spread out the support of each contributing texel, so to compensate you need more margin texels.

This is still faster than the function pointer solution, and neater.

Both versions run within the margin of error on my machine so we'll go with the simpler one.

Trying some different strategies for optimizing the decoder. The code in #ifdef 1 is slightly faster by my measurements, but a whole lot uglier.

In some situations with certain filter kernels with negative values it's possible to generate valid results > 1.0, so saturate it before we write it to make sure it doesn't overflow. Also fix incorrect filter radius while downsampling.

Add catmull rom filter. Also, move the debug asserts for values <= 1 to the very end of the process. This will make these bugs a lot harder to find, but because some filter kernels have negative values it's possible for the buffers to have values > 1 up until the point where it's converted back to an int.
