[Fredrik Höglund]

fredrik added a comment.


  The decoration parts should already be padded. The commit message in the commit that introduced the atlas (6ad4c775d7840e64a07e27d6719a3ea7c3ee5eb8 <https://phabricator.kde.org/R108:6ad4c775d7840e64a07e27d6719a3ea7c3ee5eb8>) even says so:
  "The images are separated by a row of transparent texels to minimize artifacts from oversampling."

That's the reason for the +1, +2 and +3 in the vertical positions here.
