Gtk.TextBuffer.prototype.paste_clipboard

function paste_clipboard(clipboard:Gtk.Clipboard, override_location:Gtk.TextIter, default_editable:Boolean):void {
    // Gjs wrapper for gtk_text_buffer_paste_clipboard()
}

Pastes the contents of a clipboard at the insertion point, or at override_location. (Note: pasting is asynchronous, that is, we'll ask for the paste data and return, and at some point later after the main loop runs, the paste data will be inserted.)
