Merge lp:~compiz-team/compiz/compiz.fix_1138517 into lp:compiz/0.9.9

[Sam Spilsbury]

Don't set lastFrameExtents unless the window geometry actually changed - as
that variable only exists to track changes in the actual geometry of
the window and not the apparant frame extents.

Added tests to verify that behaviour.

+1.

review: Approve

[Timo Jyrinki (timo-jyrinki)]

With this branch I couldn't resize or move Java windows (like jEdit) anymore. Reverting to the archive fixed the issue.

review: Disapprove

[Sam Spilsbury (smspillaz)]

I'm sure you meant "needs fixing" not disapprove. In any case I can have
another look into it. I didn't test with jedit but java is such a bloody
disaster that I'm not even sure I care anymore.

(or: Needs Fixing .. the problematic bzr 3616 was already reverted, but of course a proper fix could be nicer anyhow so that the 3616 could be resubmitted)

[Timo Jyrinki (timo-jyrinki)]

Sure, Needs Fixing it is.
