RayTrace bug is not in RayTrace but in Quesa, just nobody's noticed before.

Its not actually in RayTrace. If I put "return false ;" at the top  
of  e3geometry_cache_isvalid, then everything runs OK. So it seems  
there is a bug in Quesa's caching code which does not notice that the  
specular control has changed. Actually I can't see anything for  
things like the diffuse colour being changed either, so how do these  
work? Should Quesa check for the edit index of the geometry's  
attribute set? But then attributes can be in the group the geometry  
is in and in any group out from that. If someone can tell me how this  
works I can probably do the fix.
