Contributions summary:Paris primarily focused on code refactoring and optimization within the LibreOffice core repository. Their contributions included replacing instances of `sqrt(a * a + b * b)` with `std::hypot(a, b)` for improved performance and avoiding potential overflows, as well as replacing temporary value swaps and dynamic C-style arrays with standard C++ equivalents. Additionally, the user replaced `printf` calls with `SAL_INFO/SAL_WARN` calls for improved logging and converted `#define` directives to `constexpr`. The user also updated the code to utilize the standard `atanh` from `<cmath>`.
