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

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.

When downsampling start the buffer loop at -filter_texel_margin to make sure that all contributors get their taps in at the ring buffer.

Reorder these loops because I think we get a cache win if we write the entire ring buffer entry at once.

Unroll the multiply-add loops. At the cost of a function pointer dereference we get a whole lot of conditionals eliminated. Should be a solid win once the debug asserts are gone.
