Remove the ahigl example screen driver.

This example is very old, doesn't work, and confuses anyone
who reads about it into thinking that OpenGL compositing is
possible with Qt/Embedded, which is not accurate.

-  \class QAhiGLScreen
-
-  \brief The QAhiGLScreen class is the screen driver for the ATI handheld device interface.
-
-  QAhiGLScreen is implemented with the d-pointer pattern. That is,
-  the only data member the class contains is a pointer called d_ptr,
-  which means data pointer. It points to an instance of a private
-  class called QAhiGLScreenPrivate, where all the screen driver's
-  context data members are defined. The d-pointer pattern is used
-  so that changes can be made to the screen driver's context data
-  members without destroying the binary compatibility of the public
-  screen driver class.
-
-  The pure virtual functions found in the base class QScreen are
-  listed below. All must have implementations in any screen driver
-  class derived from QScreen. All are impemented in this example,
-  except for setMode(), which has only been given a stub
-  implementation to satisfy the compiler.
-
-  bool connect(const QString & displaySpec);
-  void disconnect();
-  bool initDevice();
-  void setMode(int width, int height, int depth);
-
-  The stub implementation of setMode() is not meant to indicate
-  setMode() can be ignored in your own screen driver class. It was
-  simply decided not to provide a fully implemented screen driver
-  class for the example, which would normally be tailored to your
-  device's specific requirements.
-
-  The base class QGLScreen has only one pure virtual function,
-  hasOpenGL(), which must return true if your screen driver class
-  supports OpenGL.

-    \class QAhiGLWindowSurface
-    \preliminary
-    \internal
-
-    \brief The QAhiGLWindowSurface class provides the drawing area
-    for top-level windows using OpenGL for drawing on an ATI handheld
-    device.
-
-    In \l{Qt for Embedded Linux}, the default behavior for each client is to
-    render widgets into an area of memory. The server then displays
-    the contents of that memory on the screen. For ATI handheld
-    devices using OpenGL, QAhiGLWindowSurface is the window surface
-    class that allocates and manages the memory areas in the clients
-    and the server.
-
-    When a screen update is required, the server runs through all the
-    top-level windows that intersect with the region being updated,
-    ensuring that the clients have updated their window surfaces. Then
-    the server uses the screen driver to copy the contents of the
-    affected window surfaces into its composition and then display the
-    composition on the screen.
-
-    \tableofcontents
-
-    \section1 Pure Virtual Functions
-
-    There are two window surface instances for each top-level window.
-    One is used by the application when drawing a window, and the
-    other is used by the server application to make its copy for
-    building a window composition to send to the screen.
-
-    The key() function is implemented to uniquely identify this window
-    surface class as "ahigl", and the isValid() function is
-    implemented to determine whether the associated window is still
-    acceptable for representation by this window surface class.  It
-    must either be a window using an \l {QGLWidget} {OpenGL widget},
-    or it must be a window whose frame is no bigger than 256 x 256.
-
-    The setGeometry() function is implemented to change the geometry
-    of the frame buffer whenever the geometry of the associated
-    top-level window changes. The image() function is called by the
-    window system when building window compositions to return an image
-    of the top-level window.
-
-    The paintDevice() function is implemented to return the appropriate
-    paint device.
-
-    \section1 Virtual Functions
-
-    When painting onto the surface, the window system will always call
-    the beginPaint() function before any painting operations are
-    performed. It ensures that the correct frame buffer will be used
-    by the OpenGL library for painting operations. Likewise, the
-    endPaint() function is automatically called when the painting is
-    done, but it isn't implemented for this example.
