* refactor: avoid repeating the return type from the declaration; use a braced initializer list instead [modernize-return-braced-init-list] Co-authored-by: Charles Kerr <charles@charleskerr.com> * refactor: avoid repeating the return type from the declaration; use a braced initializer list instead [modernize-return-braced-init-list] NB: using the braced-initializer list uncovered an error here: the float returned by std::floor() can't be implicitly cast to an int. This is solved by using base::ClampFloor<int>() instead. std::floor() Co-authored-by: Charles Kerr <charles@charleskerr.com> --------- Co-authored-by: trop[bot] <37223003+trop[bot]@users.noreply.github.com> Co-authored-by: Charles Kerr <charles@charleskerr.com>
