efd261bd5b fixes related to interpolation of palettes; hsv interpolation now goes 
the 'short way' around the hue circle, and the correct palette is now
chosen when > 2 palettes are present in the knots.

3147fd40d2 Support CUDA 4.1. Split filtering into new module. 
The new toolkit generates code for filtering which uses too many
registers, so this change splits filtering into its own module so that
it can have separate register usage limits during compiling. As a bonus,
this should improve startup time in general, since the filtering code
is now fixed and does not need to be recompiled.

b240fc8459 Use custom "cross" filtering. 
Sobel was giving too many false positives. This cross seems to detect
the kinds of edges we care about and avoids the rest of the image, and
it does so on pretty much everything I've tried it on. Very satisfying.

a6177edc0d Drop the RNG mult shuffle. 
It's surprisingly time-consuming, and until I have data showing that we
need it, I'm going to leave this bit of extra randomness voodoo out.

185823ad55 Rearrange the main render loop... again. 
Using one stream with two pagelocked host buffers allows us to keep the
GPU work queue full without pegging the CPU, and also reduces the
incidences where a host buffer will get overwritten before it can be
written. devtid() was flaky, so this patch also introduces a ringbuffer
to handle the 'slots' concept. It also introduces an adaptive number of
temporal samples, which improves efficiency but also killed the
assumption that (ntemporal_samples % 256 == 0), which required some
additional fixes.

5368a9254a Clamp DE radius further. 
The maximum standard deviation pushes far too hard into the limits of
the filter width, giving discrete points a weird boxy blur. The filter
slice width needs to be expanded, but that's a whole lot of coeffecient
debugging, and I'm putting it off by just reducing the maximum DE width
for now.

9049902b4f Add a crap gradient detect to make DE less bad. 
Use the vertical and horizontal gradients to "detect" when a pixel is
part of an edge that has been softened by grid-shift AA, and avoid
blurring it further. This causes occasional 1px artifacts in stills, but
fixes the truly grotesque DE bleed-out for a net win. A better edge
detector is still needed.

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.

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).
