* SUMMARY Improve performance of selection range changes viewing Scripts timeline. Whenever a selection range changes, we update all the nodes and mark them as needing a refresh. However, we only need to refresh an element if the new selection range changed the cross-section of that particular node. For example, if the selection range was showing the entire node, and is still showing the entire node, we don't need to refresh. * STEPS TO REPRODUCE 1. Inspect iCloud.com 2. Show Timelines and Reload 3. Select Scripts timeline 4. Select a time range with a lot of scripts 5. Scrub / expand / collapse / change the time range selection => poor performance * NOTES We do still want to support "sub-event ranges". If there is a long script, you should be able to put a selection range for only part of that script evaluation and see only the Profile Nodes for that cross section.
