• bzimport set Reference to bz7598.

• bzimport added a subscriber: Unknown Object (MLST).

After testing reducing colordepth from 16bit to 8bit, no visible change occured.

We (me and brion) have concluded tha the option -trim in imagemagick is the
source of the problem

Specifically, interaction between -coalesce and the way the image's coordinates are left
from the source image's -trim.

I tested this, and it seems this issue on longer exists.

closing since no one still thinks it is broken... reopen with an example if you think it is still broken.
