smokeStochTransToKBuf.png:  Shows (left to right) stochastic transparency b=8, SLAB with k=8 and b=8,
SLAB with k=8 and b=32, SLAB with k=8 and b=128, SLAB with k=8 continuous alpha and virtual bits b=32,
and hybrid transparency with k=8.

pineTreeComparison2.png:  Shows the same techniques as in Figure 5, but contains the full image for
all of the rendering techniques (not just the insets, as shown in the paper).

carStocComparison.png:  Shows a transition between stochastic transparency, SLAB, and hybrid transparency,
similar to the Foliage Map (Figure 7) or the smokeStochTransToKBuf.png image above.  The left image is
stochastic transparency, right image is hybrid transparency, and the middle images are SLAB with various 
settings.


blacksmith_?.png:  A sequence of larger images giving more context to those in Figure 3 in the paper.
The letters [a..g] refer to the position inside Figure 3.  (a) is the rightmost image in Figure 3
(i.e., stochastic transparency) while (g) is the leftmost image in Figure 3 (i.e., 8x MSAA w/ alpha-to-coverage)

blacksmithContext.png:  Shows context of the Blacksmith model, since it isn't [yet?] widely used in 
the community.  Not designed to illuminate any other point from the paper.  (Uses k-buffering with a large
number of layers.)
