Switch code to use gdk_display_is_composited() instead. The new code also doesn't use a vfunc to query the property but rather requires the backend to call set_composited()/set_rgba() to change the value.

/* A couple of notes about this file are in order. In GDK, a
|
|
* GdkScreen can contain multiple monitors. A GdkScreen has an
|
|
* associated root window, in which the monitors are placed. The
|
|
* root window "spans" all monitors. The origin is at the top-left
|
|
* corner of the root window.
|
|
*
|
|
* Cocoa works differently. The system has a "screen" (NSScreen) for
|
|
* each monitor that is connected (note the conflicting definitions
|
|
* of screen). The screen containing the menu bar is screen 0 and the
|
|
* bottom-left corner of this screen is the origin of the "monitor
|
|
* coordinate space". All other screens are positioned according to this
|
|
* origin. If the menu bar is on a secondary screen (for example on
|
|
* a monitor hooked up to a laptop), then this screen is screen 0 and
|
|
* other monitors will be positioned according to the "secondary screen".
|
|
* The main screen is the monitor that shows the window that is currently
|
|
* active (has focus), the position of the menu bar does not have influence
|
|
* on this!
|
|
*
|
|
* Upon start up and changes in the layout of screens, we calculate the
|
|
* size of the GdkScreen root window that is needed to be able to place
|
|
* all monitors in the root window. Once that size is known, we iterate
|
|
* over the monitors and translate their Cocoa position to a position
|
|
* in the root window of the GdkScreen. This happens below in the
|
|
* function gdk_quartz_screen_calculate_layout().
|
|
*
|
|
* A Cocoa coordinate is always relative to the origin of the monitor
|
|
* coordinate space. Such coordinates are mapped to their respective
|
|
* position in the GdkScreen root window (_gdk_quartz_window_xy_to_gdk_xy)
|
|
* and vice versa (_gdk_quartz_window_gdk_xy_to_xy). Both functions can
|
|
* be found in gdkwindow-quartz.c. Note that Cocoa coordinates can have
|
|
* negative values (in case a monitor is located left or below of screen 0),
|
|
* but GDK coordinates can *not*!
