The class-pairing validation added in 10ee5aef4f rejects any type
assignment whose class isn't in the buildingSMART implementer
agreement map. That map only covers physical product occurrence/type
pairs (IfcWallType -> IfcWall, etc); IfcTypeProcess and IfcTypeResource
subtypes such as IfcTaskType, IfcProcedureType and the resource types
have no entry, so previously-valid assignments like
IfcTaskType -> IfcTask were rejected with "allowed occurrence
classes: <none>".
These classes still follow the schema's universal Type-suffix naming
convention, so derive the pairing the same way the existing
ApplicableOccurrence fallback does: strip "Type" from the relating
type's class name and accept it only if the schema actually declares
that entity. This can only add pairings implied by the type's own
class name, so it cannot loosen the existing rejection of genuine
mismatches (e.g. IfcWallType -> IfcWindow).

The crease and sharp weighting seemed flipped to my sensibilities, so
now crease is heavier than sharp. I also added a commented out block
for debug colours in case someone wants to quickly use bright colours
to diagnose future problems.
Add UseEdgeClassification, RenderCreases, ValleyAngleMinDegrees,
RenderSharp, RidgeAngleMinDegrees, and RenderFlush to EPset_Drawing,
following the existing HasUnderlay/DPI/PerspectiveShiftX pattern.
The master toggle defaults off, preserving current linework output;
the three dependent controls only show in the panel once it's on.
Removes the previous dormant, transient operator-redo properties for
the ridge/valley thresholds and flush-edge toggle, which were never
persisted per-drawing or exposed in any panel, replacing them with
the persistent camera properties read in setup_serialiser().

Add svg-use-edge-classification (default off, preserving today's
linework), svg-render-crease-edges, and svg-render-sharp-edges
settings, gating the existing 5-class classification feature so it
can be disabled entirely (falling back to the pre-classification
whole-shape output) or have individual classes suppressed.
Also fixes a bug uncovered while wiring this into Bonsai: ready(),
where geometry_settings() actually gets read into the serializer,
was only ever invoked explicitly by IfcConvert's CLI driver and
isn't exposed to Python. Every Svg* setting -- including the three
from previous rounds -- silently stayed at its hardcoded constructor
default when the serializer was constructed directly through the
Python bindings, as Bonsai does. Fixed by calling ready() from
SvgSerializer's own constructor, safe since it only reads
geometry_settings() with no other side effects, and settings are
always finalized before construction in every call path.

Circular-profile IfcColumn/IfcPile elements produce a genuine
analytic cylindrical BRep face (via BRepPrimAPI_MakePrism), not a
tessellated facet. The edge classification/extraction pipeline is
edge-identity-based end to end, but a smooth surface's silhouette is
synthesized by HLR on the fly and has no corresponding pre-existing
edge to bucket, so it was silently dropped once any edge in the
product had been classified. Add a face-level pass that includes any
non-planar face directly in the outline bucket, giving HLR's
per-face OutLine reconstruction a face identity to correlate
against. Purely additive: diffing the whole test scene's output
before and after shows only the two previously-missing tangent
lines appear, nothing else changes.

Re-enable the view-relative sign flip for folds seen through an
opening (e.g. a box with a face removed), reverted in the previous
commit after it corrupted unrelated geometry. The earlier revert's
diagnosis was slightly off: bucket reassignment can't affect HLR's
own visibility computation, so the corruption was actually an
asymmetric-threshold artifact -- an unconditional flip re-tested
small, correctly-flush deviations against the much smaller valley
threshold instead of the ridge one. Gating the flip so it only
reinterprets folds that already clear their own pre-flip threshold
fixes the box case while leaving every other test object's
classification unchanged (verified against the full test scene).

Fixes three bugs in classify_edge_from_faces() found via real-world
testing against a dedicated stress-test scene (icosphere, Suzanne,
cylinders/cones at various orientations, a dihedral-angle sweep rig):
- The outline (silhouette) test used a bare sign comparison, so a face
at or near exactly edge-on to the camera could land on the wrong
side of zero and fall through to angle-based classification instead
of being drawn as outline. Now uses a tolerance band around zero,
matching an equivalent check already used elsewhere in this file.
- The signed deviation-from-flat formula was inverted (180 - angle
instead of angle), so small, genuinely near-flat facet angles came
out with a large computed deviation and always classified as
sharp/crease, never flush. This is why thresholds appeared to have
no effect. Also replaced the edge/wire-orientation-based convexity
sign (unreliable on real BRep topology, verified wrong against a
known fully-convex icosphere) with a simpler position-based test.
- A specific edge that was previously missing entirely (not just
misclassified) reappears correctly as a side effect of the outline
fix above; no separate change was needed for it.
A fourth issue (folds viewed through an opening, e.g. a box missing a
face, should read as crease rather than sharp) was attempted via a
back-facing sign flip, but reverted: it broke the fixes above broadly,
since "both faces back-facing" isn't a rare look-through-a-hole case
once HLR has already filtered to visible edges only. Documented in a
code comment for whoever picks this up next.

Adds boundary/outline/sharp/crease/flush classification of HLR
projection edges in SvgSerializer, so CSS can style silhouettes,
ridges, and valleys differently instead of drawing every edge
identically (fixes the "ugly faceted sphere" problem from #3668).
Classification happens pre-HLR on the original solid's real face
topology (three prior attempts tried to classify HLR's own output,
which carries no face topology at all and can't be correlated back
by edge identity). Each class's visible portion is then extracted via
HLRBRep_HLRToShape::VCompound(S)/OutLineVCompound(S), the same
per-shape filtering mechanism already used for per-product
segmentation, applied per class instead. Classes are tagged directly
on individual <path> elements so Bonsai's merge_linework_and_add_metadata
group-level class rewrite in operator.py never touches them.
New settings: svg-ridge-angle-min-degrees, svg-valley-angle-min-degrees,
svg-emit-flush-edges (ConversionSettings.h), wired through Bonsai's
CreateDrawing operator and exposed via its redo panel.

The Reassign Class operator refused to reassign an element to a different
IFC product family unless it was an IfcElement <-> IfcElementType swap, so a
piece of geometry mistakenly hosted on IfcSite could not be turned into
IfcFurniture even though root.reassign_class handles it fine.
Loosen the guard: only block the case that actually matters - a spatial
element (IfcSpatialElement / IfcSpatialStructureElement for IFC2X3) with no
geometry, which would be a real containment-hierarchy container rather than
a stray modelled object. Everything else reassigns freely.
Closes#8664

When converting a wall representation to a parametric extrusion via the
Representation Utilities buttons, an element that has openings would report
"has openings - representation cannot be updated" and stop, without telling
the user there is an ALT+click path that bakes the openings into the new
representation. Point the message at that path so the error is actionable.

* Bonsai: place auto-generated opening boundaries at their real position #8237
auto_generate_boundaries (single-space mode) built each opening/filling boundary
from the opening's LOCAL geometry (get_vertices) but first did
mat.translation = (0, 0, 0) on its placement matrix. Because the vertices are
local, that placement translation is exactly what carries the opening to its
real location, so zeroing it collapsed every window/door boundary onto the
origin. This is why the auto path misplaced window boundaries while the
single-element path (create_element_boundary) placed them correctly, as
@MDHering observed with the two modes. Keep the full placement matrix.
Verified on the reporter's file: the opening's real placement is (0.1, 1.5, 1.0);
a vertex went from (0.6, 0, 0) under the old code to (0.7, 1.5, 1.0) with the fix,
i.e. moved by exactly the (0.1, 1.5, 1.0) that was being discarded.

It was passing `IFC4X3` directly to `schema_by_name` which is expecting
schema identifier (e.g. IFC4X3_ADD2, not IFC4X3 allowed by `IFC_SCHEMA`
- IFC4X3 is one of the IFC4X3 iterations while it was in development,
not the final one).
