Macros
#define	FALSE   0
#define	TRUE   1
#define	SQR(x)   ((x)*(x))
	A macro that returns the square of x.
#define	DEGREE(x)   ((((x < 0)?(x)+2*M_PI:(x))*360)/(2*M_PI))
	Convert radians to degrees. The result will be in [0:360].
#define	RADIAN(x)   ((((x<0)?(x)+360:(x))*2*M_PI)/360)
	Convert degrees to radians. The result will be in [0:pi].
#define	MAX(x, y)   (((x)>(y))?(x):(y))
	A macro that returns the maximum of x and y.
#define	MIN(x, y)   (((x)<(y))?(x):(y))
	A macro that returns the minimum of x and y.
#define	ABS(x)   (((x)<0)?-(x):(x))
	A macro that returns the absolute value of x.
#define	SIGN(x)   (((x)<0)?-1:1)
	Return the sign of x.
