[virtual]

Pure virtuals that need to be implemented in order to be a grid line drawer.

Implements DtGridLineDrawer.

Reimplemented in DtUtmGridLineDrawer.

const [protected, virtual]

This is only to try and identify one grid line drawer from another to prevent unnecessary terrain redraw as a coordinate system choice changes.
