My pixmap is a little bullet. It's red and the color palette shows no
white at all when displayed in the Gimp. 

I've seen i can define a TRANSPARENT attribute to my SYMBOL giving a
index of the color palette that won't be shown.

In this case, there is no white in the color palette but all the
transparent part of the gif file appears white when rendered in the map.

I've googled a lot and read the different howto's on symbology but did
not found any interesting hints.

Do someone here have a great idea to solve the problem ?

Thanks

Didrik
