-// Interface for the display-server half of a DriWindow.

-// The main implementation of this lives in the process that owns the display
-// connection (usually the GPU process) and associates a platform window
-// (DriWindow) with a display. A window is associated with the display whose
-// bounds contains the window bounds. If there's no suitable display, the window
-// is disconnected and its contents will not be visible.
-//
-// In software mode, this is owned directly on DriWindow because the display
-// controller object is in the same process.
-//
-// In accelerated mode, there's a proxy implementation and calls are forwarded
-// to the real object in the GPU process via IPC.
