<!--
Features to add:
* make the left and right parts of the viewer independently scrollable
* make the test list filterable
** default to only showing unexpecteds
* add other ways to highlight differences other than circling?
* add zoom/pan to images
* Add ability to load log via XMLHttpRequest (also triggered via URL param)
* color the test list based on pass/fail and expected/unexpected/random/skip
* ability to load multiple logs ?
** rename them by clicking on the name and editing
** turn the test list into a collapsing tree view
** move log loading into popup from viewer UI
