description:
[svn r1702] Adding OutputSelector to the pan-n-scan widget. This is the code I use to load
up multiple projections and display them in a pan-n-scan interface:
import yt.extensions.image_panner as ip
import yt.extensions.image_panner.pan_and_scan_widget as pns
from yt.mods import *
outputs = ["output_%04i" % i for i in range(5,14)]
os = pns.OutputSelector(outputs = outputs)
os.configure_traits()

[svn r1703] This fixes a projection bug for some cases where epsilon shows up in the
dds1/dds2 calculation to get refinement factors between grids, thus changing
rounding from one value to another.
