Michel Dänzer d0cdffebe6 xwayland/present: Redirect surface window as needed for page flips
It's needed when the surface window is a depth 24 descendant of a depth
32 toplevel window.

xwl_source_validate ensures the toplevel window pixmap has valid
contents when a client reads from it, or when the window hierarchy /
geometry changes. It's never called in the normal fullscreen application
case, so there's no GPU copy overhead with that.

v2:
* Don't try to redirect a depth 32 descendant of different-depth
  ancestors, the alpha channel wouldn't be handled correctly.
