Functions
constexpr int64_t	EASYPC::DsuToNm (int64_t aDsu)
constexpr double	EASYPC::AngleToDegrees (int32_t aAngle)
constexpr int32_t	EASYPC::NormalizeAngle (int32_t aAngle)
	Wrap an angle into [0, ANGLE_FULL_TURN)
void	EASYPC::PointRotate (double aPx, double aPy, int32_t aAngle, double aCx, double aCy, int32_t &aOutX, int32_t &aOutY)
	Rotate aPx, aPy anticlockwise by aAngle about aCx, aCy as Easy-PC places points: in double with exact quarter turns, truncating toward zero, so the operand order of each sum decides the last bit.
void	EASYPC::PointRotate (int32_t &aX, int32_t &aY, int32_t aAngle, int32_t aCx, int32_t aCy)

Variables
constexpr int64_t	EASYPC::NM_PER_DSU = 100
constexpr int	EASYPC::ANGLE_FULL_TURN = 360000
constexpr double	EASYPC::COORD_LIMIT = std::numeric_limits<int>::max() / 2.0
	Half of KiCad's integer range, so shape code rotating or adding coordinates cannot overflow.
