Summary0007197: wrong comparison between doubles throughout the code
Descriptionif(x==y) for x,y floating point should be replaced by


I belive this is the reason the stream tracer filter fails when compiled with the Intel compiler (10.1 on linux OpenSuse 32bit), which is more strict on comparing floating point numbers.

gcc is able to generate a warning when floats or doubles are compared with ==. Indeed, VTK has many many such warnings.

There are several fixes and if(fabs(x-y)<eps) is one of them not not necessarily the best approach in all cases.
