Revert "Add support for 'padding-box' value for 'box-sizing' property (fixes #6032)"
This reverts commit 945adabd48
.
The CSS Working Group resolved to drop this value from the spec:
http://log.csswg.org/irc.w3.org/css/2015-05-20/#e555680
The group was unable to come up with even a theoretical use case.
Gecko only implemented this value for completeness.
Other browsers vendors have clearly expressed they have no interest
in implementing this.
