imageantialias-function has a number of limitations which is not documented.



1) Line thickness can only be 1 (since there are no real polygon fill anti-alias)

If you try to use thick lines they will be converted to lines with weight=1 when antialias is enabled.



2) You can't use styled lines. They will dissapear.



As a side note there also seems to be some instability associated with the use of antialias since PHP has reproducible crashes when this is used.

I've writen some antialiasing functions for people who don't have the requirements for the builtin antialiasing.
