Symbol rotation behaves differently for gif (GD) and png (AGG) output

Description
For png output, rotation of symbols behaves as expected.
For gif output, rotation does not seem to be around the centre of the symbol. The largest offset is for truetype symbols, but also for vector and pixmap symbols the offset seems to be more than can be explained by rounding to integer.
I attach a png and a gif that I am working on for the mapserver 6 documentation. They illustrate the differences. I also attach the map file that was used to generate the images.
