While quality settings normally have a tendency to stack up pretty
brutally, am3 is somewhat different in this respect, as it lets you get
away with lower settings on other features - provided they can be set to
produce random noise instead of biased artifacts.

For example, area lights can be set to produce random noise by turning
on jitter. If you're using am3 anyway, you can then crank down on the
other area light quality settings.

(Radiosity, on the other hand, is an example where this doesn't work, as
its artifacts are biased, not random-noise-ish.)


This comes in particularly handy when combining multiple "jitterable"
features, e.g. area lights + media + SSLT + micronormals (the latter two
always being "jittery" by nature).
