vtkProbeFilter very slow when probes are at cells with node blanking
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkProbeFilter spends lots of time (approx. 1000 x normal seed case) when probe location resides within a cell with one or more points blanked. On my Core-i7/920 it takes 1/4 second to probe such "degenerate" cell, while 1000 non-generated probes succeed within the same time. The structured 3D grid is pretty small with 250k nodes only!
