reduce the antialias strength (#13814)

Browse Source 
# Objective

- Fixes #13807

## Solution

- Before this pr we antialiased between 0.5 and -0.5. This pr changes
things to antialias between 0.25 and -0.25. I tried slightly larger
ranges, but the edge between the boxes still showed. I'm not 100% sure
this is the correct solution, but from what I could find the range you
use is more art than science.

## Testing

- Ran rounded_borders example, the code in the linked issue, and the
testing example from #12702.

---

## Changelog

- reduce antialiasing in ui shader.
