Ok - I'm not familiar enough to comment much on the swscale internals, but
this makes the output consistent on bigendian, and actually makes at least a
fully opaque alpha plane stay that way after scaling, so ok as far as I can
see.
Karma points for scaling a picture with actual alpha (not just 255 for all
pixels) and checking that it turns out right after scaling.
Yes I did test with a real alpha image :)
Updating the changelog to explain more what has been changed
swscale: fix gbrap to gbrap alpha scaling
Casting and shifting to uint16_t was incorrect, instead use the value
from the alpha plane directly.
Somehow I didn't see this improved commit message in the commit that
actually was pushed - where did the improved message go?
