Class CM3LayerGraticule extends CMLayerGraticule

CM3LayerGraticule

This class required a level of complexity beyond what I initially expected.
The problem is that we have to:
- Draw graticule lines based on the zoom level, projection, and area viewed
- Paint coordinates along the border based on where the graticules intersect with the border
- Paint coordinates along the outside of the graticule grid if it is visible (i.e. does not
intersect with the border.

Graticles are made visible by setting the overall style to transparent. The graticules must be drawn to get the intersections for the exterior and border
