ostream overload discussion
Should VTK-m objects overload <<
for ostream access?
Two of them already do, the rest are inspected via PrintSummary(std::ostream)
:
$ grep -nr "friend std::ostream" ../vtkm
../vtkm/io/PixelTypes.h:104: friend std::ostream& operator<<(std::ostream& os, const BaseType& basePixel)
../vtkm/rendering/Color.h:123: friend std::ostream& operator<<(std::ostream& out, const Color& c)
