Does gScreen support motion photos?

Motion photos (or live photos) are photos that have an associated (short) video that together form a single media item.

Google's API inexplicably gives no indication if a given photo is a motion photo or not, so the only way to make this determination is to attempt to download the photo as a video. If it passes, it's a motion photo. If it fails, it isn't.

Performing this check preemptively on your entire media library is out of the question, because that would mean downloading every single photo.

Instead, gScreen builds up this information gradually. Every time it downloads a photo (when a viewer requests it), there's a 20% chance it will perform a motion photo check. The result of this check is recorded, so it never has to be performed for that media item again.

The upshot is that you will only see the photo component from motion photos when you set up gScreen for the first time, but you will see more and more video components as time passes and gScreen builds up this information gradually.
