[FEATURE SUGGESTION] DistanceMeasurementsPlugin surface pointer

[g-rodigy]

Describe the solution you'd like When hover surface pointer must change not only color, but and form to square oriented paraller surface. At least for start to describe the algorithm, I will try to do it.

Describe alternatives you've considered Trimble Connect web version

Additional context

So, I calculate it as difference between Сamera vector converted to euler angles and surface normalVector eurler angles, but limit additionally very large angle for css transform. Probably there is a better solution, because I don't know very well 3D mathematics.

Just sharing an idea: if you have 2 vectors in 3d - camera vector and surface's normal vector:

1. calculate an acute angle between them both
2. calculate a cross product for these vectors to get the axis of rotation
3. rotate the square using calculated acute angle and calculated axis of rotation

Question if we want to add such option, or is it too specific for xeokit-sdk? :)

We don't currently have requirement for this ourselves on our roadmap.

However we would consider a PR if somebody wanted to contribute it as a helper component, similar to something like src/extras/PointerLens, that could be configured on the measurements plugins.
