Right now, extension specific actions on window positioning are implemented by wrapping the ScreenRec's PositionWindow() proc pointer: the extensions are storing the original pointer in their private data and putting in their own one. On each call, their proc restores the original one, calls it, and switches back again. When multiple extensions doing so, they're forming a kind of daisy chain. (the same is done for lots of other procs) While that approach is looking nice and elegant on the drawing board, it's complicated, dangerous like a chainsaw and makes debugging hard, leading to pretty blurred API borders. This commit introduces a simple approach for letting extension hook into the window positioning path safely, w/o having to care much about side effects with the call chain. Extensions now can simply register their hook proc (and an opaque pointer) and get called back - w/o ever having to mess with the ScreenRec's internal structures. These hooks are called before the original vector (usually handled by DDX/screen driver directly) is called. Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net> |

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.
