If alpha is zero then sneakily replace it with a very small nonzero so that the color data is preserved.
...
Pre-process n1 so that we don't have to do it later on. Can't do n0 since it's used to find the coefficient index.

Report downsample progress by when we empty the ring buffer, it's more accurate that way.

Rearrange the algebra on two of the filters to avoid repeating decimals which cause precision loss. Use int32 to test filters because it's more accurate.

Use input_h + pixel_margin * 2 to prevent progress report from ever going above 1. Always report a 0 before and a 1 at the end of each resize.
