It is possible to implement setSmooth for CSFML, however, it will be a more complex task than doing the same in the SFML library. This is because CSFML is a wrapper for the SFML library, so you would need to be familiar with the underlying C code of CSFML and the SFML library, as well as Rust programming language. Additionally, you will need to be aware of any potential compatibility issues that could arise from making changes to both libraries. If you are familiar with C and Rust, then it should be possible to implement setSmooth for CSFML.
