Description

Currently the SelectionManager works as expected for selecting triangle representations of surfaces.

However when we have surfaces represented with triangle strips we need to be more careful and find the correct triangle indices from the strips.

To see the issue you can start by modifying the viz_selection.py tutorial and add actors that use strips such as streamtube and then try to select those and start debugging the issue.

Contributor guide

Research direction
Investigate how triangle strips are stored in the pipeline and modify the selection manager to map strip indices to actual triangle indices. Start by examining the viz selection.py tutorial and add streamtube to see the breakdown.
