In a lot of window or graphics systems, drawing an arc is different from the 
way people usually think. It is defined as 45 degree from the line x=0 to the
line pointing to the up right corner. I just know it is because it is more
efficient. What is the algorithm? On the other hand, if I had a point on an arc
create by this algorithm, how could I decide the angle?

any comments are welcome and appreciated.
