Bug 78372 - create multiple windows with offset

[Jasper St. Pierre]

The rationale explained in the bug by Pekka and Emilio sounds OK to me.
Explaining a bit more about your use case with your data visualization app
might be helpful.

What kinds of systems do you want your app to be run on? Generic desktop
systems? If so, then you can't guarantee anything about utilizing hardware
overlays, as the user might be watching a video at the same time, which
should take HW overlay priority over your application to prevent a YUV ->
RGB conversion in software.

If you have a special usecase like a Bloomberg terminal, then making your
own shell and shell protocol like the IVI team is doing might be a better
solution, so you can guarantee window position and HW utilization. The
default desktop-shell is very much designed for desktop Linux use cases,
where we don't want to expose global window positions or make any
guarantees to the client about where they are on screen, precisely so you
don't assume you are the only user of the HW.
