Iterator over non-const VDB primitives on a geometry detail.
At least until GEO_PrimVDB
becomes a built-in primitive type (that can be used as the mask for a GA_GBPrimitiveIterator
), use this iterator to iterate over all VDB grids belonging to a gdp and, optionally, belonging to a particular group.

gdp | the geometry detail over which to iterate |
group | a group in the detail over which to iterate (if nullptr , iterate over all VDB primitives) |
filter | an optional function or functor that takes a const reference to a GU_PrimVDB and returns a boolean specifying whether that primitive should be visited (true ) or not (false ) |
