Do you know what these clipsToBounds calls are doing? Removing them has no
effect.

[fs, 2016/09/08 21:08:11]

The reason that they have no effect is because they are always true in this
code-path (and all the others where it's used.) In a near future that will no
longer be true though, but each removal has its time =)
