 // The GPU process is agnostic as to how it displays results. On some platforms
 // it renders directly to window. On others it renders offscreen and transports

 //
 // The ImageTransportSurface class defines an simple interface for events that
 // should be responded to. The factory returns an offscreen surface that looks
 // a lot like an onscreen surface to the GPU process.

 // The ImageTransportSurfaceHelper provides some glue to the outside world:
