9b03f557c2 Fix missing control points in async version. 
The allocation pool was reallocating the same frame as soon as it had
left the current scope, before it had been copied. We just reallocate
the same chunks. I don't think this has any real performance impact but
this can be verified.

095936666e 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.

618b51b1b1 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).

e9998c28da Re-add a hard clamp for an estimator minimum. 
The value 0.4 is above what it should be (0.3 is the theoretical minimum), and
having the harder clamp threshold causes some problems, but fixes others.
There's a deeper bug here.
