[vtkusers] vtkOpenGLGlyph3DMapper does not pass vtkInformation to the ScalarsToColorsPainter

[Jenya Burstein]

Hello,

It appears that the vtkOpenGLGlyph3DMapper constructor is missing a method
call of passing its PainterInformation to the ScalarsToColorsPainter
memeber.

As a result, calling methods of the vtkMapper class, such as
selectColorArray(), SetScalarModeToUsePointFieldData(), etc, has no effect
on the plot.

Adding a single line
"this->ScalarsToColorsPainter->SetInformation(this->PainterInformation);" at
the bottom of the vtkOpenGLGlyph3DMapper constructor fixes things up.

Do I understand correctly the problem and the way it should be fixed?

If so, what is the best way to submit the change to VTK? How long should we
expect for the approval to take?

Best Regards,
Jenya
