Protected Member Functions
virtual QString	labelForHorizLine (const DtPoint &val, double increment, const DtTerrainDatabase *db)
	Override to provide different labels for the vertical or horizontal grid lines.

	Since horizontal and vertical labels are the same, default implementation calls labelForHorizLine.

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