Description

Is your feature request related to a problem? Please describe.

The watermark module only allows one to add a watermark at a certain position.

Describe the solution you'd like

It would be nice to have an option to repeat the watermark to cover the whole image. I.e., use the watermark as a tile that can be repeated until the whole image is covered.

Alternatives

One can use multiple instances, but this is tedious and hard to use to achieve a consistent result.

One can also create SVG files where a pattern is repeated, but this does not scale easily to multiple watermarks.

Research direction

Start by locating darktable's watermark module and reading how it currently positions a single watermark over an image. Compare the requested tiled behavior with the existing positioning options and the SVG pattern alternative described in the issue. Done means an option can repeat the watermark to cover the whole image consistently.
