[yt-users] reading gadget-2 binary/hdf5 format

[Matthew Turk]

Hi Semyeong,

Looks like the bounding box is getting confused somehow, and it's seeing it
as the same value for left/right edge.  I think your ordering of the bbox
is correct (if it weren't, then changing the ordering to be [[-bbox_lim,
-bbox_lim, -bbox_lim], [bbox_lim, bbox_lim, bbox_lim]] would fix it) but
I'm not sure why it's failing.
