Remove a sync from iter.
...
A small but consistent improvement.

Actually asynchronous rendering.
...
This change didn't affect GPU performance at all, but it did improve CPU
startup time, and should also improve time for long-running animations.

Speed enhancement: alpha packing.
...
When the alpha channel is used in a color palette, the code now replaces
the blue channel in the accumulation buffer with a pair of two U16s,
which encode the values of the blue and alpha channels as a fraction of
the value of the density. When the alpha channel is always 1.0, the blue
channel works as normal. Density is now always the last element in the
accumulation buffer.
Eliminating the separate IO operations improved total runtime by more
than 30% on my card, while the extra calculations reduced that to 20%
when alpha was present (though that can be optimized further).
