Description

Hey all, I'm pretty new to Iced, just wanted to say thanks for the work you're doing.

I noticed the quality of antialiasing on WGPU was worse than Glow, and was wondering if there is any way to tweak the settings further beyond antialiasing: true?

Research direction
Investigate the antialiasing settings available in Iced's WGPU backend compared to the Glow backend. Look into the relevant rendering code in the `wgpu` and `glow` backends (likely in `iced wgpu` and `iced glow` crates). Check if additional MSAA settings or sample count options can be exposed to users. Review existing comments and the codebase to understand the current antialiasing implementation and propose improvements.
