gvr::BufferViewportList
#include <gvr.h>Convenience C++ wrapper for the opaque gvr_buffer_viewport_list type.
Summary
This class will automatically release the wrapped gvr_buffer_viewport_list upon destruction. It can only be created via a GvrApi instance, and its validity is tied to the lifetime of that instance.
