    UBSan claims this is undefined behaviour...

    I don't believe them, but I'll fix it anyway.

    Don't use the C99 restrict keyword because MSVC is apparently still
    more than 25 years behind the C standard.

    Add most const decorations.

    Not sure what macOS is doing, but it looks like something weird is
    happening in interpolate_width... maybe some unexpected integer
    promotion?

    Log Message:
    Use uint64_t instead of double for interpolation.

    More effort to fix the macOS issue. This could potentially result
    in slight problens with the rightmost pixel, but will protect
    against any weird FP issues and -ffast-math concerns.
