You seemed to have gotten the impression that I suggested we blend
each surface in either sRGB or linear depending on it's encoding.
That's not what I was suggesting. The compositor won't pick it's
blending gamma space per surface. It's either completely linear or
sRGB. So all clients with the same alpha values (and colors) will look
equal independent of their gamma encoding. We should probably expose
the blending gamma space, so clients have a chance to adjust their
translucent parts, even if most of them will ignore it.
Actually what you say is EXACTLY what I was suggesting.
If all the clients have identical-looking shadows, it is because they
all wrote the same numerical values to their images in the shadow area.
Even if they use different compositing rules for the opaque regions.
