Jorge Rodriguez 1d5c902e2e These minor optimizations were probably already done by the compiler but they can't hurt.

Jorge Rodriguez 969ff7c850 Make sure calculate_memory matches with the allocations. Fix some errant asserts.

Jorge Rodriguez 4b69c0637e If alpha is zero then sneakily replace it with a very small nonzero so that the color data is preserved.

Jorge Rodriguez d510d70b6a Report downsample progress by when we empty the ring buffer, it's more accurate that way.

Jorge Rodriguez 43fbc1d5e3 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.

Jorge Rodriguez ca241daefa Use rounding to try to preserve the original value. Fix test case.

Jorge Rodriguez 145690788c 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.
