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.

Some minor ports for Linux. No idea how it worked at all in Windows with STB_RESIZE_IMPLEMENTATION instead of STB_RESAMPLE_IMPLEMENTATION.

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.
