CQisRound

DataType: CQisRound

Use:
	Stores information about a round polygon (a polygon with many vertices which looks
	like a circle).

Members:
	StructName (const char*) : Points to a buffer containing the parent cell name.
	Layer (unsigned short) : Stores the layer number.
	DataType (unsigned short): Stores the datatype number.
	CenterX (CQisMetric) : x-coordinate of the center of the circle.
	CenterY (CQisMetric) : y-coordinate of the center of the circle.
	Radius (CQisMetric) : radius of the circle.
	ArcRes (double) : angle in degree subtended by each segment between 2 vertices of the
	polygon. This determines the smoothness of the round polygon or how close the
	polygon is to a circle. The smaller the ArcRes, the smoother the polygon.
	ArcRes = (360 / number of segments) degrees.

Note:
	- This data cell is only used to add a round polygon. When QisLib returns data to the
	user, round polygons are returned as CQisBoundary.
	- Refer to the 'SUPPORT & COMPLIANCE' section to learn about maximum layer:datatype
	numbers.
