This is a follow-up PR to #11352 (not yet merged) that adds vector time-frequency visualizations. The referenced PR will have to be merged first.
The proof of concept and explanation of how the vectors are visualized is here: https://gist.github.com/alexrockhill/58c4316415c54fcc24f85a617862e2bf. In summary, the three independently estimated orientations are scaled by their phase (0 degrees full magnitude, 180 degrees full negative magnitude) and summed. This makes it so that an oscillation at a vertex appears as a vector oscillating between forward and backward with zero magnitude in the middle. This method does not introduce any rotating vectors as far as I can tell (see gist), any rotations are likely due to the changing orientation of the oscillation.
