test patch

Hi,

I have try to add some missing features to dib but I am not as skilled as max
and it is a very long time that I have not code in C.
If someone can test my patch and give me feedback.
The patch contain:
Ellipse
GetDirection
SetDirection
SetDCPen/Brush

round rectangle, arc, pie, chore is coded but arc have a big todo in it.
and I use it in other part. So this function is alpha supported.

I have try to use the optimised algo of ellipse drawing to have good
performance.
Else I can do a working algo but not optimised quickly.

I really try to just bring my little stone to dib patch if it is too buggy just
throw it to rubbish or give me feedback and I will try to fix it.

thanks,
Olivier
