Subject: [PATCH] Fix image layout tests with newer PHPUnit versions

`assertSame` uses a stricter epsilon since version 9.5.14 (absolute
`PHP_FLOAT_EPSILON`), see https://github.com/sebastianbergmann/phpunit/pull/4874.
Just rely on the recently introduced `Helpers::lengthEqual` for length
comparison.
