Interpolating points (#3002)

Browse Source 
* Add a class for rendering an interpolated point cloud (WIP)

* Make sure that we render the correct number of points

* Group interpolation properties into a property owner

* Update interpolation stuff (which was broken :) )

* Prevent interpolation from breaking with only one step or invalid interpolation values

* Add trigger properties for controlling interpolation

* Allow setting start interpolation value from asset

* Implement spline-based interpolation

* Cleanup, and interpolate to start and end

* And asset type documentation

* Add example asset

* Handle missing data values in interpolation

* Always show values at the knots, if there is one

* Experiment with more dynamic rendering (batching)

* Speed up interpolation by doing it on GPU instead of CPU

* Bring back spline interpolation (this time on GPU)

* Refactor initial data buffering

* Add a helper function to compute transformed positions

* Use vec3 positions instead of vec4 (less data to transfer)

* Update interpolation value documentation

* Apply suggestions from code review

* Increase interpolation speed max value

* Fix faulty indentation

* I banish thee, redundant empty line
