[yt-users] draw_ids

[David Collins]

This is about what I expected.  So why and or how do I have these two
slices with grid ids that are the same, but clearly not the same grid? The
below shows two slices from the same simulation, but notice that number 169
is a level 2 grid near the center in the first plot, and a level one grid
near the edge in the second plot.  The grid with id =169 is a level 1 grid,
but seems to have RightEdge that's consistent with the center of the center
of the box.
