490e647e23c0ccba6e594493660d12788817f35f Have Wuffs output to BGRA, not indexed color
This lets us set the yet-to-be-decoded pixels for a partially decoded
image to be transparent. Prior to this commit, we decoded to an indexed
color buffer, which was not guaranteed to be able to represent
transparent pixels.
This is also one step towards fewer post-decode passes. The current
model has multiple separate passes: SkSwizzler handles expanding pixel
indexes to BGRA and subsetting / scaling, SkWuffsCodec handles blending
potentially transparent pixels over the previous frame and skcms handles
color correction. The long term plan is to remove the SkSwizzler from
that chain.
