For the initial render or while zooming CAIRO_FILTER_NEAREST is used
for responsiveness.Once you stop zooming and the corresponding settings
are enabled (they are by default) a second pass will redraw the image
with CAIRO_FILTER_GOOD shortly afterwards.
It makes no difference if you have eog running in fullscreen or
windowed mode, btw.
