- **PCB print-outs**: `SilkScreenDrawingProvider` prints one page of everything that has a
silkscreen outline. Split it into top and bottom pages, filtered by side, the same way
`TraceMaskDrawingProvider` gives one page per `PCBLayer`.
- **PCB print-outs (done)**: `SilkScreenDrawingProvider` prints the top side, and a second page for
the bottom when a part is mounted there, so a project without bottom parts still prints one page.
`SilkScreenFilter` takes the side: a part with a Board Side goes on its own side's page, parts
without one count as top, and board outlines go on both pages so that they line up. Neither
page is mirrored or captioned, the same as the trace-mask pages.
