As far as I can figure out, the isosurface code relies on global 
variables (yuck!) that aren't initialized until after parsing, so method 
2 isosurfaces can't be traced during the parsing stage. Fixing it would 
probably involve a lot of modification to the isosurface code, and there 
really isn't much point when 3.5 will have a highly improved version.
