The class QuakeView from Listing 6-3 extends the built-in class GLSurfaceView , which provides
a surface for rendering using OpenGL. QuakeView also includes the following classes:
 QuakeRenderer : An inner class that creates a simple OpenGL renderer,
which can be used to call native functions on the C engine. This class
provides the following events:
 onDrawFrame : This event fires whenever the renderer draws a frame
and is used to perform OpenGL API calls. It has one argument:
GL10 , the interface to the OpenGL context. In a pure Java game,
this context will be used to perform GL API calls; however, you are
rendering everything in the native side so this parameter is not used.
