/**
* SECTION:mir_interaction
* @Short_description: Mir backend-specific functions
* @Title: Mir Interaction
*
* The functions in this section are specific to the GDK Mir backend.
* To use them, you need to include the <literal>&lt;gdk/gdkmir.h&gt;</literal>
* header and use the Mir-specific pkg-config files to build your
* application (either <literal>gdk-mir-3.0</literal> or
* <literal>gtk+-mir-3.0</literal>).
*
* To make your code compile with other GDK backends, guard backend-specific
* calls by an ifdef as follows. Since GDK may be built with multiple
* backends, you should also check for the backend that is in use (e.g. by
* using the GDK_IS_MIR_DISPLAY() macro).
* |[
* #ifdef GDK_WINDOWING_MIR
* if (GDK_IS_MIR_DISPLAY (display))
* {
* /&ast; make Mir-specific calls here &ast;/
* }
* else
* #endif
* #ifdef GDK_WINDOWING_X11
* if (GDK_IS_X11_DISPLAY (display))
* {
* /&ast; make X11-specific calls here &ast;/
