There is also an API breakage for any code that uses initializer lists to
initialize Cairo::Matrix, for example this code (taken from BMPx) no longer
compiles against 1.8.0 (and the second line will cause crash at runtime if
compiled against 1.6.x):

Cairo::Matrix matrix = { 1, 0, 0, -1, 0, h };
cr->set_matrix (matrix);
