[Ves] VES on the Desktop

[Pat Marion]

The example programs are indeed hardware accelerated.  VES links to the
system GL library, see OPENGL_gl_LIBRARY in your CMakeCache.txt.  For
example, on my machine it's /usr/lib/x86_64-linux-gnu/libGL.so, which means
the examples will use your system GL driver (like nvidia for example).

Thanks for pointing out the 100% CPU bug.  That's easily fixed- delete line
221 in vesTestHelper.h:

  glutIdleFunc(vesTestHelperGlobals::idle);

The examples use the GLUT to manage the OpenGL context and receive
keyboard/mouse input.  In vesTestHelper.cpp, line 221, a glut idle callback
is initialized, even though it's not actually used for anything!
