Plot dialog:
- "Units" (millimetres / inches) is the page setup's own unit: the offsets
and the custom scale are shown in it, the stored ratio converts with it
so the plotted result and the paper space's unit stay the same
- "Custom: [paper] mm = [drawing] units" spells the picked scale in that
unit and accepts a typed ratio, which selects the list's name for it or
becomes a ratio entry of its own
- "Hide paperspace objects" is the page setup's plot-hidden flag; it is no
longer derived from the "Hidden Line" shade mode
- "Save changes to layout" (paper layouts, on by default) writes the dialog
into the layout when a plot is sent; previews never touch it
- offsets are labelled in the page-setup unit and kept in millimetres in
the file
System variables (typeable, through SETVAR, listed by SETVAR ?):
- PLOTOFFSET, PAPERUPDATE, PLOTROTMODE, PLOTTRANSPARENCYOVERRIDE and
BACKGROUNDPLOT live with the persisted plot preferences: the plot origin
counts from the printable corner unless PLOTOFFSET says the paper edge;
a printer that does not list the sheet either warns or switches to its
default sheet; transparency can be forced on or off; BACKGROUNDPLOT bit 1
is the dialog's background switch and bit 2 drives batch plots
- CTAB and TILEMODE read and switch the current layout
Tests cover every new control and variable; six new strings in all 21
locales; the Plot dialog grows to 940×690 for the two extra rows.

A drawing saved by a commercial CAD application (tests/fixtures/plot,
provided by Panos: one 10 m line, three layouts) corrects several
assumptions of the previous commit:
- rotation is relative to the medium's own orientation: an unchanged sheet
keeps the driver's exact medium (its PDF driver lists landscape media of
its own, written with rotation 0; a system printer's portrait A3 plotted
landscape carries 90); only a newly picked sheet is written as the
catalogue's portrait medium
- the stored scale factor (DXF 147) is the ratio × 25.4 on millimetre page
setups and the plain ratio on inch ones; the "use standard scale" bit
stays clear for standard and custom scales and is set for fit-to-paper;
a standard code is kept across a paper-unit conversion ("1:1" on an
inch page setup over a millimetre paper space is 1 in = 25.4 units)
- layout plots take the same scale path as every other area, so a foreign
layout's paper-space unit survives
- "plot with plot styles" / "display plot styles" round-trip as the
dialog's checkboxes, independent of a style table being named
- layout limits place the sheet at minus its displayed margins, the way the
source application does (the printable corner is the paper-space origin);
the margin ↔ rotation mapping shared by the printable-area guide now
turns the medium's top margin into the layout's left one at 90°
The fixture round-trips through the dialog with every stored field
unchanged; picking a new sheet on it writes the canonical form.
