Normal resize mode was not something I was planning on supporting in precise. Nevertheless, I've merged in some work I did a few weeks ago to essentially fix it up so that there's no tearing and windows don't appear to jump around when you resize them.

There is still a race condition in the window decorators where pixmaps can be freed server side before they are bound by the decorator. Getting around that race condition requires some synchronization protocol which I've prototyped and works fine with gtk-window-decorator (no fail to bind errors \o/). However, I don't want to push up the size of the diff anymore. So I've put that work in another branch (lp:~smspillaz/compiz-core/compiz-core.decor_synchronization).

The damageScreen call in DecorWindow::resizeNotify is, while unfortunate, necessary for now at least. There are some race conditions to do with bindPixmapToTexture where the returned size can differ from the actual texture size in the middle of a resize op. As such, damageScreen for now.

I hope this is the last revision we need to do of this.
