Zoom bicubic

The images below are good examples of the difference between bicubic- and lineair-zooming. Bicubic zoom is set to 'automatic' by default, see the Settings window.
As you can see, lineair zooming just enlarges the pixels, while bicubic zooming uses an interpolation algorithm to render the image.
