[Paraview] ParaviewWeb 4 - WebGL renderer camera reset and background issue

[Bogdan Daqui Herrera]

Hello all,

I have run into a couple of issues while using the WebGL renderer in
ParaviewWeb 4. Could you help me out with some pointers or possible
workarounds for these problems.

1. Camera View being reset
The camera orientation and position are always being reset after
performing different operations, such as:
-Activating/De-activating the scalarbar
-Choosing between point/face data for the ColorBy selection
-Adding a filter into the current pipeline
-Rescaling
-advancing to the next file/time-step in the Data Source.

2. Background other than black
This happens when a background of a different colour, for example a
gradient of white and grey is chosen. If I alter the camera position or
orientation, this background (which is in this case represented by a
rectangle with the selected colours) can move out of the field-of view,
it does not stay in a fixed position relative to the camera meaning the
black regular background is in most part visible.

Both issues happen only when using the WebGL renderer. When switching to
the software renderer, the behaviour is as expected.

Kind Regards,
Bogdan
