New issue 1303: Boolean Containers only work for 3D objects https://bitbucket.org/yt_analysis/yt/issues/1303/boolean-containers-only-wor... chummels: In trying to create the intersection of a `Ray` and a `Region` object, yt fails because Boolean operations only exist for 3D selection data containers. It seems like it should work for 1D or 2D data containers with 3D datasets too, but maybe this is harder than I am imagining.
