Lines rendered by vmatrix environment are misaligned

[chrisjpurdy]

The vertical lines rendered by the vmatrix environment are segmented into 3 parts, with the middle segment bolder and misaligned from the others. The issue seems more obvious with larger matrices. These lines should be uniform if possible.

(La)TeX code:

\begin{vmatrix}
   0 & -1 & 1 \\
   -1 & 0 & 1 \\
   -1 & 0 & -1
\end{vmatrix}

Environment

• KaTeX Version: 0.16.0 (version on katex.org)
• Device: Desktop
• OS: Windows 10
• Browser: Firefox, Edge, Chrome
• Version: 101, 102, 101

Turning off Microsoft ClearType doesn't make a noticeable difference.

Example on Chrome:

FWIW, I can't reproduce this on Chrome on Windows 10. I think it depends on your monitor resolution/DPI and zoom level (though I couldn't reproduce at any zoom level). I'm on a 4K display and get this at 100%:

I didn't notice it was an issue on first load (Chrome on Win 10, 1920x1080 monitor), but after zooming in then back out, the issue showed around 120% and also at 100%:

Indeed, should be fixed by #3686, released in 0.16.1. Thanks!
