Starting OpenGL 4 (above L3.2) in Mac OS X

* Starting Point for Learning

> Follow the instructions in http://www.opengl-tutorial.org. Very good. Almost perfect except for a few things listed below

>> download the normal version
>> uncompress
>> cd build; 
>> cmake -G Xcode .. (to use XCode IDE)

> Don't forget to include the following line to make OpenGL work properly in Mac OS X Maverick.

  glfwWindowHint (GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

> Fix in the fragment shader program:

   texture2D -> texture
>> The texture coordinate uv is somehow inverted in the code to use DDS texture. So it is OK for DDS. Otherwise, you need to fix the code by yourself.

> The mouse control in Tuturial06 did not work. I don't know why yet. Simply change it as you like.

> Get version info

  const GLubyte* renderer = glGetString (GL_RENDERER); // get renderer string

  const GLubyte* version = glGetString (GL_VERSION); // version as a string

  printf ("Renderer: %s\n", renderer);

  printf ("OpenGL version supported %s\n", version);

* rotation/translation/scaling transformation with GLM

glm::vec3 axsis = glm::vec3(1.f,0.f,0.f);

glm::mat4 newRot = glm::rotate(X, angle, axis);

> new Rot = X * Rotation(angle, axis)
