PointShader implementation

[khangharoth]

Hi is PointShader impl is done or under process and if not
              what are the issuses to keep in mind so that i can try to write one and than will post it for review.

   One more thing In Jogl i am not able to use gl.glPointSize(float ) when i am not using  gl.glBegin(GL.GL_POINT);
               Well what i intended to do was , if i am drawing any  LineStrip with   gl.glBegin(GL.GL_LINE_STRIP);  with say 4 vertices ,
            i should be able to render those 4 vertices diffrently than the whole lineStrip.

     Am i doing something wrong or in different order.
