Detailed Description

Struct with all the member data of the Grid (useful during serialization of an openvdb grid)

Note

The transform is assumed to be affine (so linear) and have uniform scale! So frustum transforms and non-uniform scaling are not supported (primarily because they complicate ray-tracing in index space)

No client code should (or can) interface with this struct so it can safely be ignored!
