[Feature Request] Auto adjust sample distances when FPS is dropping

[daker]

What feature or change would you like to see made?

in vtk.js, the volumeMapper has a feature called AutoAdjustSampleDistances, which allows you to interact with the volume even if the FPS is dropping, vtk.js will adjust the sampling until it gets the desired FPS.

You can do that by calling renderWindow.getInteractor().setDesiredUpdateRate(30)

Volview logic

Example using Volview

Why should we prioritize this feature?

This feature will allow the user to interact with 3D volume even if the FPS is dropping
