Prepare the access of GetData(). This process may include some computations (e.g. cpu smooth normals). Note: Resolve may be called in parallel from multiple threads across buffer sources, so be careful if it uses static/shared states among objects. Returns true if it resolved. If the buffer source has to wait some results of other buffer sources, or the buffer source is being resolved by other threads, it returns false.
Implements HdBufferSource.
Reimplemented in HdVtBufferSource.
