/// @dev Note:
/// - The ERC721 standard allows for self-approvals.
/// For performance, this implementation WILL NOT revert for such actions.
/// Please add any checks with overrides if desired.
/// - For performance, methods are made payable where permitted by the ERC721 standard.
/// - The `safeTransfer` functions use the identity precompile (0x4)
/// to copy memory internally.
///
/// If you are overriding:
/// - NEVER violate the ERC721 invariant:
/// the balance of an owner MUST always be equal to their number of ownership slots.
/// The transfer functions do not have an underflow guard for user token balances.
/// - Make sure all variables written to storage are properly cleaned
/// (e.g. the bool value for `isApprovedForAll` MUST be either 1 or 0 under the hood).
/// - Check that the overridden function is actually used in the function you want to
/// change the behavior of. Much of the code has been manually inlined for performance.
