The current approach to adjust the icon size of dash items is rather expensive: the size of each item is changed from largest to smallest, until the height of the dash fits the maximum available height, so quite some ClutterTextures are created and disposed. A better approach is to calculate the required size beforehand and only change the icon size when necessary. https://bugzilla.gnome.org/show_bug.cgi?id=636156
