I agree that it makes more sense to do it in the unity8 server.

However, the screencast plumbing cannot be used as is as qtmir
implements Compositor not DisplayBufferCompositor. The screenshots
obtained would be recomposed using our default compositor which wouldn't
match qtmir compositor output.

Since the screenshotting will be done in unity8 shell on the server
side, I think its easier to just implement the required functionality in
qtmir (i.e. dumping it's display buffer) directly instead of trying to
adapt the screencast plumbing.

Adapting it would require qtmir to at least implement
DisplayBufferCompositor and DisplayBufferCompositorFactory.
