[vtkusers] "Visualization Toolkit generated SLA File" what is it?

[Alex Malyushytskyy]

vtkSTLWriter ads "Visualization Toolkit generated SLA File"
at the begining of binary and STL file
(vtkSTLWriter.cxx, line 80

Also there is a macro
 vtkDebugMacro("Writing ASCII sla file");
in
void vtkSTLWriter::WriteAsciiSTL(vtkPoints *pts, vtkCellArray *polys)


I assume it was supposed to be STL
Could anybody of the developers make the change to these 2 lines?

Regards,
