In order to fix the above bug the interpolation default was turned off (interpolate = gFalse in Gfx.cc)

The core problem is that the cairo backend only seems to do either full bilinear interpolation or none (nearest neighbour) while it should ALWAYS filter during minification and either interpolate or edge smooth during magnification. Until this is available they should put the interpolation default back on.
