[vtk-developers] compiler warnings, float vs double

[David Cole]

You are trying to eliminate warnings, so just change the constants to the
correct type to match the methods. That is a no-op as far as everybody else
is concerned.

If you change the signatures of methods unnecessarily, others may have to
change their client code to keep pace. (For some clients and some methods
this may be a *huge* amount of work.) If there were a "*better*" reason to
change the signature, I'd say open it up for discussion, but not just to
eliminate warnings.

Change the constants unless some other people speak up and disagree with
me....
