title: Matrix stacks in OpenGL deprecated?
body: <p>I just read this:</p>
  
  <p>"OpenGL provided support
  for managing coordinate transformations and projections using the standard matrix stacks
  (GL_MODELVIEW and GL_PROJECTION). In core OpenGL 4.0, however, all of the functionality
  supporting the matrix stacks has been removed. Therefore, it is up to us to provide our own
  support for the usual transformation and projection matrices, and then to pass them into our
  shaders."</p>
  
  <p>This is strange, so how do I set the modelview and projection matrices now? I should create
  them in the opengl app and then multiply the vertices in the vertex shader with the matrices?</p>
