Use structural similarity #30

Thank you, this is terrific. I was aware of SSIM when I wrote imgmin but ImageMagick didn't have it available at the time. This is likely the single biggest improvement than can be made to imgmin, I want to add it when I have time. |
Sounds like amazing sauce. 👍 |

I've made my SSIM implementaiton usable directly in C (ignore the CLI tool that reads PNG, just set bitmaps directly via C API).
This is much more accurate than ImageMagick's MSE metric.
It may even be faster, because my implementation doesn't need to re-decode source image (you can set it once and only swap modified version).
