No answers up to now. I suppose this means it is just not implemented in a way that the
pixmap-format and the anti-alias-factor can work together. I.e. that the downscaling of anti-alias
method does not care about transparancy and as it is done after the creation of a transparent
png, the transparancy is lost.

Could that be added as a bug (or a wish for an enhancement)?

Cheers,
Joram
