As Mike has pointed out, there don't seem to be any perfect values.
However, we can minimize "Problem #2" by reducing the
FactorMultiplier. I noticed rc2 has it at 2*256. That's way too much
and makes #2 even worse. Small values are good in this case. I have
found 0.1 to be a good value. It still doesn't make the problem go
away, but it reduces the chances of it happening, and reduces how much
is actually clipped. I think 0 is supposed to work, but it creates a
new z-fighting problem that looks more like traditional stitching.
