[Patches] IsoView Patch

[iwsmith at cct.lsu.edu]

The attached patch will allow IsoView to work with the version of  
IsoSurfacer in the stable cactus release. Although the patch seems to  
remove some necessary bounds checking, it actually doesn't. Due to  
IsoView's rather inventive (read: poor) redesign that I did, the  
normal data is *not* read from IsoSurfacer, but rather somehow  
generated from the vertex data (and not through the traditional  
methods, through a totally accidental occurrence). Regardless, this  
accidental method does sort of work, if there is enough interest in  
IsoView we should consider recoding this section of it.
