Added GLES 1.x spinning cube-rendering code to eglbringuptest The coordinate, color and index data are uploaded to server-side buffers by the CGLES1Cube::KhrSetup function. CGLES1Cube::KhrPaint just sets the view matrix and issues a draw command. Which demo to display can be selected by passing its name on the command line, e.g. eglbringuptest vgline eglbringuptest gles1cube If no name is provided, the application defaults to vgline.
