[Insight-developers] More on Adaptors vs Filter precision

[Lorensen, William E (CRD)]

Luis,
I believe that I am the culprit on the adaptor/filter precision problems. A couple of weeks ago, I
added an explict cast to double on all the image filters that used arthmetic. I thought this was an
sgi'ism. Turns out it was an sgi loader problem that requires -lm after each --lVXLNumerics.

I will remove the cast to double (since I broke them). This will fix, I believe, the precision
"problem".
