Since reallocating the backing pixmap can fail, we need to try and do it before any other side effects of reconfiguring the window happen. This changes the ConfigNotify hook to return status, and moves the composite window reconfiguration wrappers to ConfigNotify. They all basically did the same thing, so we can drop the MoveWindow, ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do all the work. If reallocation fails we fail before we send any confiureNotify events, or enter the area we can't recover from. The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers that don't use this should probably deal with it in their pixmap allocate if they don't already. This also breaks ABI, so we need an alternate fix for older servers, working on the X server makes me realise why I'm a kernel hacker.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
