This filter is found in the image window menu under
Filters → Map → Paper Tile.
This filter cuts the image (active layer or selection) into several
pieces, with square form, and then slides them so that they, more or
less, overlap or move apart. They can go out image borders a little.

“Paper Tile” filter options
Division
X, Y and
Size parameters are linked, because filter starts
cutting image before it displaces pieces; so, piece size and
number of pieces in horizontal (X) and vertical (Y) directions
must be convenient to image size.
Movement
Max% is the maximum displacement percentage
against side size of squares.
Wrap around: As tiles move, some can go
out image borders. If this option is checked, what goes out on
one side goes in on the opposite side.
Fractional Pixels
Because of image cutting, original pixels can persist. There are
three ways treating them:
Background: Remaining pixels will be
replaced with the background type defined in the following
section.
Ignore: Background Type option is
not taken into account and remaining pixels are kept.
Force: Remaining pixels will be cut
also.
Background Type
You can select the background type that will be used, if the
Background radio-button is checked, among
six options:
Transparent: Background will be
transparent.
Inverted image: Background colors
will be inverted (255-value in every color channel).
Foreground Color: Remaining pixels
will be replaced by the Foreground color of Toolbox.
Background Color: Remaining pixels
will be replaced by the Background color of Toolbox.
Select here: When this radio-button
is checked, clicking in the color dwell will open a Color
Selector where you can select the color you want for
background.
Centering
If this option is checked, tiles will rather be gathered together
in center of the image.
