[Daniel Holbert [:dholbert]]

This is a very slight mismatch on a single pixel at the top left corner of a rounded text input widget.

The testcase has rgb(197,197,197). Reference case has rgb(196,196,196)

The rest of the border (in both files) is mostly rgb(191,191,191), but this one pixel is lighter as a result of being an antialiased curve, I think (and very slightly lighter in the testcase than in the reference case).

This seems to be the same as Bug 1470546 and Bug 1471455 (though in a different testcase).
