Details

This is the API that older versions of Edge used for implementing the screenshot WebDriver command.

There's an example of it being used here: https://github.com/ocalvo/WorkTests/blob/96cebbdd794ee25d1bb7b5e279f743ae9e06143e/MediaTestManaged/DCompHelpers.cs

The summary of it is that you ask for a visual to be rendered and then wait on an event for that to be done. It seems like a reasonable API but it's a bit unclear what the performance would be like.
