Attachment: XUL testcase

I'm trying to create a thin bar with rounded (circular) ends for bug 462113, and found I get different results on 1.9.1 and 1.9.2 for a given moz-border-radius.

Testcase attached, with 4 variations of a black bar with rounded ends. Top to bottom:

1) 8px tall, 3px border radius
2) 8px tall, 4px border radius
3) 7px tall, 3px border radius
4) 7px tall, 4px border radius

In all cases, the 1.9.2 rendering is blunter (less curvature) than on 1.9.1.
#2 on 1.9.2 looks like #1 on 1.9.1, and #4 on 1.9.2 looks like #3 on 1.9.1. I'm not completely sure which on is correct, but I suspect 1.9.2 is... #2 should have precisely circular ends, but looks pointy on 1.9.1.

This seems to be fixed now. A late-march 1.9.1 build was still showing the problem, but a current build does not.

Might have been bug 456219.
