point is that this is for handling *non*-premultiplied alpha (since

fix MSVC-ARM internal compiler error by wrapping malloc
...
For some reason Microsoft CL compiler for ARM is unable to compile malloc when parameter is an expression. malloc(x * y) will cause internal compiler error, malloc(x) is however fine.

original code having bugs or deviating from
the specification

My guess is people who care about premultiply also care about color space.

Do the multiply inline, it should be a tad faster and not corrupt our data.

Specify a channel as having premultiplied alpha and use it to un-premultiply all other channels before resampling.

When doing a perfect po2 nearest neighbor downsample don't allow -0.5 and 0.5 to both contribute to a texel or you'll get a double tap.

Add a test suite to do a bunch of different resizes to find problems. One problem found was an incorrect calculation of texel support how many margin texels needed when downsampling. When downsampling we need to spread out the support of each contributing texel, so to compensate you need more margin texels.
