Detailed Description

struct CFBD_GraphicArc;

Represents a circular arc defined by center, radius, and angular range.

An arc is a portion of a circle specified by a center point, radius, and a pair of angles defining the start and end of the arc.

Arc definition:

• center: The center point of the circle from which the arc is drawn
• radius: Distance from center to the arc edge, in device units
• start_degree: Starting angle in degrees (0-359)
• end_degree: Ending angle in degrees (0-359)

Angular convention:

• 0° points horizontally right (3 o'clock)
• Positive angles sweep counter-clockwise
• Angles are automatically normalized to [0, 359]
• If start_degree > end_degree, the arc wraps around 0°
