title: Rendering problem with the OpenGL GL_POINTS primitive
body: <p>When using software rendering, or any graphics card in our developlment office, our little coloured GL_POINTS render in exactly the colour we expect.  Out in the field, some users report points rendered in the wrong colours.  Getting them to turn off hardware acceleration fixed their problem, so we've been putting the whole thing down to a third-party issue and using a workaround (tiny pixel-sized rectangles whose colour remains unproblematic). The snag: we are taking a huge performance hit.</p>
  
  <p>My question is, has anyone else had a similar issue, and, if so, did they come up with a way to keep their GL_POINTS <em>and</em> get the colour right?</p>
