[Paraview] [EXTERNAL] Is anyone using the Extra Headlight in ParaView?

[Moreland, Kenneth]

The use case Alan brings up is captured in bug 17236: https://gitlab.kitware.com/paraview/paraview/issues/17236. Until that bug is fixed, I would argue strenuously against disabling the headlight. The implementation of the bug fix may or may not require the headlight to stick around (depending on how it is implemented).

I don’t personally have any other use case for the headlight, but it is a convenient way to get a bright light shining directly on the view. It’s valuable to quickly illuminate an object where the shading has made the colors murky. Is there a compelling reason to get rid of it? It’s tucked away in an innocuous corner of the GUI.

No objection here.  Only thought I have is that the lights may be setup by default slightly differently for 2d and 3d.  We may want a “headlight” for 2d.

By default, Paraview illuminates the scene with a vtkLightKit<http://www.vtk.org/doc/release/5.0/html/a01682.html>. You can however add an extra headlight. I am about to add a more general capability which lets you add any number and any kind of light, including the headlight. When I do that, the semi-hardcoded extra headlight becomes redundant. I would like to remove it to streamline both the code and the UI.
Are there any objections to me doing that?
