Remarks

The surface to render into. The surface is assumed to be associated with the display and as such is still driven by vsync signals such as those from android.view.Choreographer and that it has a native refresh rate matching that of the display's (typically 60hz).

NOTE: Due to the shared, cooperative nature of the render thread it is critical that any Surface used must have a prompt, reliable consuming side. System-provided consumers such as android.view.SurfaceView, android.view.Window#takeSurface(SurfaceHolder.Callback2), or android.view.TextureView all fit this requirement. However if custom consumers are used such as when using SurfaceTexture or android.media.ImageReader it is the app's responsibility to ensure that they consume updates promptly and rapidly. Failure to do so will cause the render thread to stall on that surface, blocking all HardwareRenderer instances.
