[vtkusers] vtkErrorMacro and vtkOutputWindow

[Andy Cedilnik]

Since I was the one who recently modified vtkErrorMacro and vtkWarningMacro,
I will try to help you.
For me warnings and errors seems to work perfectly.

First of all, try to write a small program that will generate an error and 
warning.
What I suggest is to try to for example read the file that does not exist:

vtkPNGReader r
r SetFileName "/tmp/whatever.png"
r Update

This should generate error.
Similar way you can generate warning. You will have to grep on the VTK code.

If this works, then you have problem in your code.
