D14783: [scenes/opengl] Correctly draw shadows when corner tiles are missing

zzag added a comment.


  Maybe, it makes more sense to squash D14783 <https://phabricator.kde.org/D14783> and D14784 <https://phabricator.kde.org/D14784>.

For example, take a look at this texture atlas, here's bottom tile is wider than top tile.
