Request to mention Document size in the docs section

[Izaakthegreat]

Gingerbread will misalign the silkscreen and drills on export (not in preview) if document size is exactly the dimensions of the Edge.Cuts layer. Either could be patched or could add a warning in the Docs that document size always needs to be a little bit bigger than the Edge.Cuts layer. Not too large however, a full A4 sheet on a 6hp Eurorack panel crashed the export.
