/**
 * @dev Extension of TRC-721 with the TRC-2981 NFT Royalty Standard, a standardized way to retrieve royalty payment
 * information.
 *
 * Royalty information can be specified globally for all token ids via {TRC2981-_setDefaultRoyalty}, and/or individually
 * for specific token ids via {TRC2981-_setTokenRoyalty}. The latter takes precedence over the first.
 *
 * IMPORTANT: TRC-2981 only specifies a way to signal royalty information and does not enforce its payment. See
 * https://eips.ethereum.org/EIPS/eip-2981#optional-royalty-payments[Rationale] in the ERC. Marketplaces are expected to
 * voluntarily pay royalties together with sales, but note that this standard is not yet widely supported.
