title: How to overlay GLSurfaceView over a CameraPreview in Android?
body: <p>I am trying to merge two examples from the ApiDemos so one overlay over the other.<br>
  1. CameraPreview.java<br>
  2. TranslucentGLSurfaceViewActivity.java<br></p>
  
  <p>I guess GLSurfaceView is not really necessary, I saw demos that uses a GL layer as a Camera PreviewCallback, but since I am such a noob at OpenGL, I am kind of lost. Can someone points me toward the light (figuratively speaking)?</p>
