Wallpaper image mode:
<literal>center</literal>: Center the image on the background. If it is too small, it will be surrounded by a black border.
<literal>fill</literal>: Like <literal>scale</literal>, but preserves aspect ratio by zooming the image until it fits. Either a horizontal or a vertical part of the image will be cut off.
<literal>max</literal>: Like <literal>fill</literal>, but scale the image to the maximum size that fits the screen with black borders on one side.
<literal>scale</literal>: Fit the file into the background without repeating it, cutting off stuff or using borders. But the aspect ratio is not preserved either.
<literal>tile</literal>: Tile (repeat) the image in case it is too small for the screen.
