priority of layers, points

[Nate Reed]

I am using PHP MapScript and am wondering how to overlay lat/lon lines 
last, so that they are on top of some point layers.

The current sequence is:

- Turn on selected raster layers, lat/lon layer
- Draw map ($map->draw)
- Draw points ($point->draw)

As I understand it, you have to the draw points after you draw the map.  
Is there another option I have not considered?

I know the point layer can be drawn directly from the shape file, but the
algorithm is fairly complicated.  We have different symbols for different
wind directions, scaling of font sizes, and more rules that would be hard
to specify in the MAPFILE.

Thanks,
Nate
