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.

A hand-written DXF small enough to read: one layout viewport at a 1:2
paper-per-model scale, one line, circle, arc, bulged lightweight
polyline, spline and block instance in model space, and one associative
aligned dimension per feature drawn on the sheet through the viewport.
Each association exercises a different part of the chain and feature
resolution: endpoints on a line, quadrants on a circle, endpoints on an
arc, an endpoint and a bulge segment on a polyline, a tangent-to-spline
reference (the 115448 shape), a viewport -> insert -> line chain through
a block instance, and an intersection with a second object chain. Every
association is marked trans_space, so all of them fail on the pre-PR3
resolver and all of them are expected to resolve now.
The expected values are checkable by hand: the viewport maps model
(x, y) to paper (150 + (x - 150)/2, 100 + (y - 150)/2), so a 100-unit
model length is 50 paper units and must still display as 100.
Verification tests come in the next pass; the fixture is committed now
so they have something to read.

Include decoded IMAGE/OLE content in the shared PDF plotting path,
with clipping, transforms, transparency, draw order, and resource reuse.
Use named page content for export and printing.
