 That is a cairo bug similiar to the one here:
 http://www.nabble.com/Bug-drawing-PNG-images-with-transparency-tf2033165.html#a5601225
 
 The bug isn't fixed yet (cairo 1.3.10), so I guess somebody should
 file a bug report on freedesktop.org bugzilla.

+Same problem as ColorMatrix (#80323). We need to pre-multiply alpha
+before giving the raw data to Cairo.
