I just want to share a problem with cl-gd or maybe gd itself
i don't know...

Has anybody tried to   draw an ellipse which starts  and ends
at a precise angle?
Well, I have and it turns out that the angles that i have 
specified are not drawn exact , they are either bigger or
smaller and SOMETIMES theyy are correct!

is this a problem with gd  or cl-gd?

example
I draw an ellipse that passes through two points
then I want this ellipse to start from exactly one of the two point
aand end at the other one. I calculate the angles with tthe help
of the function (atan) or (asin) using the coordinates of
the center of the ellipse and the two given points...

and the angles drawn don't match with the given points
That's funny!!! ridiculous!!!
There's always 1 or 2 maybe more degrees discrapency 
between the angles drawn and the given points


Anybody encountered the same thing?
