Changed this back to PP_Resource to avoid constructing a pp::Buffer_Dev using
the PP_Resource ID from the CDM-- seems silly to pass the C++ version around
when all we want to do is pass the resource ID back through the PPB proxy
interface.

                     const PP_DecryptedBlockInfo& decrypted_block_info);
   void DeliverFrame(pp::Buffer_Dev decrypted_frame,
                     const PP_DecryptedBlockInfo& decrypted_block_info);
