Before we fixed the clone's position everytime it was allocated, eg. whenever we would scroll a pixel. Insetad we listen on the WindowActors allocation signal, which happens far less as we don't move the WindowActor around much.

/**
|
|
Scrolled and tiled per monitor workspace.
|
|
|
|
The tiling is composed of an array of columns. A column being an array of
|
|
MetaWindows. Ie. the type being [[MetaWindow]].
|
|
|
|
A Space also contains a visual representation of the tiling. The structure is
|
|
currently like this:
|
|
|
|
A @clip actor which spans the monitor and clips all its contents to the
|
|
monitor. The clip lives along side all other space's clips in an actor
|
|
spanning the whole global.workspaceManager
|
|
|
|
An @actor to hold everything that's visible, it contains a @background,
|
|
a @label and a @cloneContainer.
|
|
|
|
The @background is sized somewhat larger than the monitor, with the top left
|
|
and right corners rounded. It's positioned slightly above the monitor so the
|
|
corners aren't visible when the space is active.
|
|
|
|
The @cloneContainer holds all the WindowActor clones, it's clipped
|
|
by @cloneClip to avoid protruding into neighbouringing monitors.
|
|
|
|
Clones are necessary due to restrictions mutter places on MetaWindowActors
|
|
MetaWindowActors can only live in the `global.window_group` and can't be
|
|
moved reliably off workspaceManager. We create a Clutter.Clone for every window which
|
|
live in its @cloneContainer to avoid these problems. Scrolling to a window in
|
|
the tiling can then be done by simply moving the @cloneContainer.
|
|
|
|
The clones are also useful when constructing the workspace stack as it's
|
|
easier to scale and move the whole @actor in one go.
