World File Details

[Kyle Mulka]

Hi guys!

So, which pieces of free software support the second and third fields of 
world files? I've heard that most software just ignores rotation because 
it is too complex to implement or something. Will mapserver take a world 
file with rotation and actually rotate it?

If any software does actually do this, I guess I would then need to 
somehow georeference these rotated images. How would I go about doing 
that? I don't want to maintain two images: one for the map, one for the 
way I want it unless there is some automated way of keeping these two in 
sync.

Another related question: Is it possible to display a map with mapserver 
or similar software that is rotated... where north is not up, but some 
other direction like pointing to the lower left of your screen?
