Hi, guys: As current design, android use compositor SurfaceFlinger to composite application's window surface to framebuffer as its base graphic policy, but for some special application such as full-screen running games, we can sometimes to render into the framebuffer directly, by-passing the second pass of compositing, when we get the enough knowledge of this window's attribute (no alpha, full screen, top layer etc...). For me don't want to reinvent the wheels, so is there any design already? Or, may you have any suggestions about what modules need to be modified (WindowManagerService? SurfaceFlinger? Gralloc?) to satisify this requirement. Thanks very much.
