Actually, they stay constant. they use pixel coordinates to display by.  
The symbols are always the same size no matter the zoom level.  The 
gridding is applied to the image pixel coordinates, not the MapServer 
coordinate space.





Can you convert your grid points into polygons and do a polygon fill?

Would add a lot of complication and excess data to the process, I only 
need to track the center point right now for example.  It really needs 
to be a symbol, as the grid of points is generated dynamically.
