Any interest to update FoxToolkit bridge tp recent VTK versions?

Dear Fox'ers,

My app exists since 2005 and was from the start designed with the 
FoxToolkit for UI design and VTK (https://vtk.org/) for 3D visualization 
(VTK is a cutting edge visualization toolkit for scientific application).
The bridge between FoxToolit and VTK uses *vtkfox*, originally written 
by Doug Henry, to which Pietro Cerutti applied some updates about 10 
years ago (https://github.com/gahr/vtkfox) to make it compatible as VTK 
library evolved (I also applied some very minor modifications).

Basically, *vtkfox* provides a canvas widget class (FXVTKCanvas) and an 
interactor class (vtkFXRenderWindowInteractor) that allows VTK to 
interact with FOX application. Keyboard and mouse events are translated 
to allow for "native" VTK functionality.

*vtkfox* perfectly does its job for any FOX version (both in 1.6.x and 
1.7.x branches), but currently only for VTK version up to VTK6.1 update 
(it uses OpenGL version 1.2 only, which leads to rather poor 
visualisation performance compared to nowadays' standard).
So I want to update to a more recent VTK version that supports recent 
OpenGL versions.

I successfully compile and link my app with the recent VTK8.2 version, 
but it fails at runtime with the following errors:
- "failed to get valid pixel format."
- "GLEW could not be initialized: Missing GL version"
- "Shader object was not initialized, cannot attach it."

After many tests, I came to the conclusion that these errors are related 
to *vtkfox*, which would probably need some update to be compatible with 
recent VTK versions (it evolved deeply since version 6.1).
I have tried fixing these errors, but failed to do so (I am not a true 
software engineer, only a scientist with some coding skills ;-) ).

Anybody would be interested in helping to bridge recent VTK versions to 
the FoxToolkit?
Either updating vtkfox or aware of any another solution?
That would really be great :-)
I can easily provide a minimal example to anyone who would like to give 
it a try.

Regards,
Pof
