-// The "GPU plugin" is currently implemented as a special kind of
-// NPAPI plugin to provide high-performance on-screen 3D rendering for
-// Pepper 3D.
-//
-// On Windows and X11 platforms the GPU plugin relies on cross-process
-// parenting of windows, which is not supported via any public APIs in
-// the Mac OS X window system.
-//
-// To achieve full hardware acceleration we use the new IOSurface APIs
-// introduced in Mac OS X 10.6. The GPU plugin's process produces an
-// IOSurface and renders into it using OpenGL. It uses the
-// IOSurfaceGetID and IOSurfaceLookup APIs to pass a reference to this
-// surface to the browser process for on-screen rendering. The GPU
-// plugin essentially looks like a windowless plugin; the browser
-// process gets all of the mouse events, because the plugin process
-// does not have an on-screen window.
-//
-// This class encapsulates some of the management of these data
-// structures, in conjunction with the AcceleratedSurfaceContainerManagerMac.
