Restore after save state fails because of direction being serialized as an object

[bourdaisj]

Seems like direction is stored as a Float64Array, JSON.stringify serializes it as an JS object :(
Therefore when restoring we have a failure since it tries to feed an object into macro.setArray
I'll fix it

Good catch! Do you anticipate this being a fix into vtk.js or Glance? vtkObj.toJSON() implies the output should be JSON-serializable, but right now it definitely is not.

[bourdaisj]

yeah I guess vtkObj.toJSON is broken right now? did not think about that.
And we may want to fix getState as well since it should return a representation that should be directly JSON-serializable (e.g., returning plain JS array instead of typed array where applicable)

[bourdaisj]

we may have nothing to fix here in Glance indeed
