support negative x and y?

[ShuaiGao]

When i draw a line(point A to point B) or set a pos(x,y), can i use negative x or y?

Just like python list index, positive is from left to right, negative is right to left. Its easy to draw a right border just like left border.

Why not try it and see if it works?

I was tried, but it doesn't seem to work. It's been too long, now i didn't need it.
