Rounded corners not working for Diamond shape

[f0rsakeN-afk]

Description:
When the "rounded" option is enabled for diamond shapes, the corners remain sharp instead of becoming rounded. This issue affects visual consistency, especially when other shape types support corner rounding.

Expected Behavior:
Diamond shapes should render with rounded corners when the "rounded" option is selected.

I've implemented rounded corners for diamond shapes at level 1 sloppiness, but haven't yet added support for the other two sloppiness levels. Would you prefer I open a pull request now with just the level 1 implementation, or wait until all three levels are supported?

Let me know what works best!

Hey @f0rsakeN-afk
I would like to see the PR for this. Because there is one edge case here which I would like to see whether you have covered it or not.
