Auto merge of #15122 - anholt:webgl-premultiply, r=emilio

webgl: premultiplication, y flipping, and format conversion

<!-- Please describe your changes on the following line: -->
This series implements a bunch of the texture unpack path features for WebGL.  There are known issues with big-endian systems noted in the comments, but I don't know of a clean way to cast from `Vec<u16>` to `Vec<u8>` (which, if we had one, would make this code much cleaner anyway).
