Motivation
PNG output is the only one that can handle polys without turning them into tets first
As such it's convenient to output a field on the poly mesh
But for polyhedra, being limited to the XY plane means translating and rotating the mesh at initialization, which is just too much. It would be easier to get PNG output to work better in 3D
Design
Add more parameters for sampling on an arbitrary rectangular region with PNG output
Impact
Easier to work with PNG output
Easier to output polyhedral results until exodus is supported directly
