ObjGfx40 Unit
Draws a curve
Declaration:
procedure ogCurve(x1, y1, x2, y2, x3, y3:int32; segments:uInt32; colour:uInt32);
Remarks:
Draws a curve from (x1,y1) through (x2,y2) to (x3,y3). Segments is the
number of line segments to divide the arc into. The higher the number
the smoother the line, but the longer it takes to render.
