Odd behavior with worklets using virtual coordinate arrays
Some worklets (see vtkm/worklet/testing/UnitTestVoronoi.cxx
in this branch) are passed invalid, zero values when given an input domain array that is obtained from the coordinate system of dataset. Commit f052e4cfd3c87911b86705b4e66eedd59f460761 exhbiits the problem and b772838e0c1752d119a83e163032936f5912c832 demonstrates a workaround by copying the coordinate array to one with a default storage tag.
