This reverts commit a9238292. It also reverts follow-up commits: 87755d04 c2c710e5 cc8a76ce The new implementation is much too slow because it will cause each section of the border image to be uploaded to the atlas, and it will not be shared between different border images nor between different sizes of the border. The performance regression is so significant that it's not worth it for the original bug fix. We leave the tests around, so some of those might regress due to this.
