It places crop marks (cutting lines) between objects to facilitate post-print trimming.
The macro streamlines complex layout tasks that would otherwise require manual duplication and alignment. Its key features include: Oberon Object Tiler
When compared to its contemporaries, the Oberon Tiler was an outlier. The classic Mac OS and Windows championed overlapping windows as an intuitive metaphor for a physical desktop. The RISC OS had a more disciplined approach but still allowed overlap. Even UNIX environments like X11 with twm or fvwm defaulted to overlapping. Only specialized research systems like Plan 9’s rio window manager or the earlier Cedar system explored tiling, but none made it as central or as seamless as Oberon.

🖥️ In an age of ultra-wide monitors, manual window management is inefficient. A tiler ensures that not a single pixel is wasted, filling the screen with usable data rather than empty desktop wallpaper. The classic Mac OS and Windows championed overlapping
tiles = [Tile("grass"), Tile("stone"), Tile("water")] tiler = ObjectTiler(canvas_size=(800, 600), layout=GridLayout(cell_size=32))
For each tile, sort its list of object indices by layer (or actual depth). Because list lengths are short, an insertion sort or a network sort is faster than a quicksort.
