Enable views to be placed in windowless surfaces.
For purposes of parcelling SurfaceControl to embed view hierarchies across
processes. We also want these Surfaces to receive input, but we can't
let the clients call setInputWindowInfo directly (or we could have issues
with clients stealing focus, etc...) and so we provide a method
blessInputSurface which has the WM configure a surface for input with
a minimal and safe set of parameters.
