Description

Given the EllipseStd value, returns the Center Point, From Angle, Central Angle, Rotation Angle, semi-Major axis length, and Minor Axis to Major Axis Ratio for the Elliptic Arc.  These are the same parameters used by PutCoordsByAngle to create the Elliptic Arc.  If EllipseStd = TRUE, the From Angle is relative to the rotated semi-Major Axis rather than the X-Axis.
