[PATCH weston v3 03/13] tests: add sub-surface protocol tests

Thu Apr 25 03:57:43 PDT 2013
For testing the protocol behaviour only:
- linking a surface to a parent does not fail
- position and placement requests do not fail
- bad linking and arguments do fail
- passing a surface as a sibling from a different set fails
- different destruction sequences do not crash
- setting a surface as its own parent fails
- nesting succeeds
