An initial implementation based on AMD's FFX SPD (Single Pass
Downsampler).
Apart from requiring STORAGE_IMAGE support for the image format, the
following limitations are in place due to FFX SPD:
- Image must be 2D or 2D array (including cube maps)
- Image must be single-sampled
The following _can_ be supported, but not yet implemented:
- sRGB formats
- Integer formats
- depth/stencil formats

This most strongly affects the Vulkan back-end which uses a hash map
to cache VkPipelines. It also should speed up some parts of the D3D11
back-end.

We were not respecting the terms of the license that this piece
of code requests for redistribution.
I noticed this when investigating adding a new third_party library
and wanted to display its license in about:credits. This change
adds a special file that the licnese check in Chrome uses and
fixes the naming of the README for this script.
