Provide screenshot suggestions

[desiderantes]

Generating screenshots for applications would be a really nice feature, and creating a safe default picture in case there's something wrong with other screenshots.

There's discussion about this feature here, but the implementation discussed has the following problems:

• Depends on X11 tooling (I have no info on Wayland alternatives)
• Provides barebones GTK+ theming (I guess this is where Houston would shine)
• Does not deals with apps with long startup time, apps with initial steps before the main window, nor apps with required configuration

We've discussed this before, but the result is usually the same: Auto-generating screenshots will almost always yield a worse result than the developer (who knows their application and which screens are useful to users) taking and picking them. Given that, I don't know that the tooling required to automatically take screenshots (plus the edge cases it introduces) is worth investing time and effort into right now.

There's also the problem of apps being content-less. A screenshot of an empty Video player isn't very interesting. I'm leaning towards this being a "Won't fix" since it's far less effort to just instruct the developer to take a screenshot
