Thicken the whole image

If the slider is set to 2 Thicken Lines thickens the raster image as follows. If it finds lines on the image that are one pixel wide it adds two extra pixels, one on either side. If it finds lines on the image that are two pixels wide it adds one extra pixel.
As you move the slider from 0 to 2 you will see thin raster lines on the image being thickened in the Preview Window.
