shade and -gif

[Helge Avlesen <avle@xxxxxxxxx>]

Hi,
I sometimes need to look at numerical artifacts in my model, so I zoom in
to rather small details - is there a small bug in the shade command when
combined with the -gif option? The output I get from the below script
is different with and without the -gif option, can anyone else
reproduce this?
