Since we're not setting the frame's output shape any more, it doesn't make sense to calculate the output shape based on the frame window. Instead, track the client window directly and calculate the output shape based on that. https://bugzilla.gnome.org/show_bug.cgi?id=644930

/* At a high-level, a window is not-visible or visible. When a
|
|
* window is added (with add_window()) it is not visible.
|
|
* show_window() indicates a transition from not-visible to
|
|
* visible. Some of the reasons for this:
|
|
*
|
|
* - Window newly created
|
|
* - Window is unminimized
|
|
* - Window is moved to the current desktop
|
|
* - Window was made sticky
|
|
*
|
|
* hide_window() indicates that the window has transitioned from
|
|
* visible to not-visible. Some reasons include:
|
|
*
|
|
* - Window was destroyed
|
|
* - Window is minimized
|
|
* - Window is moved to a different desktop
|
|
* - Window no longer sticky.
|
|
*
|
|
* Note that combinations are possible - a window might have first
|
|
* been minimized and then moved to a different desktop. The
|
|
* 'effect' parameter to show_window() and hide_window() is a hint
|
|
* as to the appropriate effect to show the user and should not
|
|
* be considered to be indicative of a state change.
|
|
*
|
|
* When the active workspace is changed, switch_workspace() is called
|
|
* first, then show_window() and hide_window() are called individually
|
|
* for each window affected, with an effect of META_COMP_EFFECT_NONE.
|
|
* If hiding windows will affect the switch workspace animation, the
|
|
* compositor needs to delay hiding the windows until the switch
|
|
* workspace animation completes.
|
|
*
|
|
* maximize_window() and unmaximize_window() are transitions within
|
|
* the visible state. The window is resized *before* the call, so
|
|
* it may be necessary to readjust the display based on the old_rect
|
|
* to start the animation.
|
|
*
|
|
* window_mapped() and window_unmapped() are notifications when the
|
|
* toplevel window (frame or client window) is mapped or unmapped.
|
|
* That is, when the result of meta_window_toplevel_is_mapped()
|
|
* changes. The main use of this is to drop resources when a window
|
|
* is unmapped. A window will always be mapped before show_window()
|
|
* is called and will not be unmapped until after hide_window() is
|
|
* called. If the live_hidden_windows preference is set, windows will
|
|
* never be unmapped.
