 // Implementation of the platform window. This object and its handle |widget_|
 // uniquely identify a window. Since the DRI/GBM platform is split into 2
 // pieces (Browser process and GPU process), internally we need to make sure the
 // state is synchronized between the 2 processes.
 //
 // |widget_| is used in both processes to uniquely identify the window. This
 // means that any state on the browser side needs to be propagated to the GPU.
 // State propagation needs to happen before the state change is acknowledged to
 // |delegate_| as |delegate_| is responsible for initializing the surface
 // associated with the window (the surface is created on the GPU process).
