Convert launcher icons to cairo surfaces
This improves support for HiDPI by loading properly scaled surfaces for launcher and drawer icons. It also Fixes the Show Desktop wncklet to show a surface icon. Other wncklets have their icons determined by libwnck, so they remain as pixbufs. Fixes mate-desktop/mate-desktop#314
