Investigate Replay Based Visualization

[vzyrianov]

Getting some gaze visualizations might be easier by doing them during a Replay.

The plugin in the Visualization/ReticlePlugin/ReticlePlugin folder is the simplest example of this. During a study, displaying a reticle can be distracting. However, during the replay the reticle can serve as a useful visualization tool.

A more complex example might be to overlay a heatmap on a web browser (for example, with a chrome plugin) that scrolls along with the website during a replay.

Its unclear how useful a Replay is for visualization which makes this a potential topic to look into.
