Description Michael Kenzel 2012-02-12 17:02:35 PST

In Technical FAQ 9.030 (http://www.opengl.org/resources/faq/technical/transformations.htm#tran0030) it says:

  "If exact pixelization is required, you might want to put a small translation in the ModelView matrix, as shown below:

     glMatrixMode (GL_MODELVIEW);
     glLoadIdentity ();
     glTranslatef (0.375, 0.375, 0.);"

As far as my understanding goes, the OpenGL rasterization rules define texels and pixels to already be aligned perfectly.
So this should actually be exactly the wrong thing to do.
I would suggest this part to be removed.
