Disabling rounded rectangle antialiasing in software renderer

[elipsitz]

I'm using Slint with Rust on a microcontroller, using the software renderer.

It would be nice if there were some way to disable rounded rectangle antialiasing. It's cool that the feature is there, but with a low resolution screen, the antialiasing looks a bit rough -- blurry, instead of smooth. I'd prefer having the option of having crisp, pixelated borders and fills.

I think there is indeed something bad about the rendering of rounded rectangle that look a bit bury. The solution might be to fix the rounded rectangle algorithm rather than disabling it.
