A surface is something you can attach a buffer to. It's not a window but a wrapper for anything which might need a buffer. E.g. a cursor image. That's what you use in this test.

You can create a window from a surface by creating a wl_shell or xgd_shell surface (note it's also called a surface) from it. This will on KWin side then create a ShellClient which represents a window. And I think that's what you want to test as that's what needs to be scaled.
