Functions

Builds the box layout for a class’s inheritance diagram: a list of columns (left = most distant ancestor, right = cls itself), each column a list of display-name labels stacked top-to-bottom.

Only the class’s PRIMARY (first-listed) base is walked further up its own ancestry chain (one box per generation, single-file) – additional direct bases (multiple inheritance) each contribute exactly one box, placed in the column immediately left of cls alongside the primary base’s nearest ancestor, fanning in to cls. This covers both the common single- inheritance chain (e.g. OdGiDrawable -> OdNwObject -> OdNwDatabase) and simple multiple inheritance (e.g. Box : Shape, IDrawable) without attempting to lay out full diamond/deep-multi-inheritance graphs.

Rasterizes a column-of-boxes inheritance layout (see build_inheritance_columns) into a simple box-and-arrow PNG. Own visual style, not a byte-for-byte clone of any third-party tool’s diagrams – shared between the ODA and Default renderer families.

Returns:

Raw PNG bytes.

Produces a filesystem-safe, cross-platform slug from a logical filename.

Neutralizes every character Windows forbids in a filename (< > : " / \\ | ? *) plus .. traversal, so a malformed entity/namespace name – or an overloaded C++ operator function whose own name IS one of these characters (confirmed crash: operator| produced function_operator|.html, rejected by Windows with Invalid argument during a real Kernel SDK render) – can never produce an illegal or output-directory-escaping path. Kept deliberately minimal so it matches the pre-existing per-family behaviour for every ordinary name and only adds* uniform escaping the per-language _resolve_base_filename hooks don’t already cover (some handle */& themselves for C++ pointer/ reference types; re-escaping here is idempotent, a harmless no-op for characters already gone by the time this runs). A single trailing extension (.html/.md) is preserved and the intentional __ scope separator is left intact.

Produces a safe HTML id attribute value from a raw entity name.

Unlike sanitize_filename_slug, this targets HTML id semantics, not filesystem safety: a primary template’s display name carries its formal parameter list with literal </>/whitespace (e.g. "MockExchangeTraits< kMock2Ifc >") – valid inside a double-quoted HTML attribute per spec, but the whitespace and angle brackets break #id-style CSS/JS selectors and anchor-link ergonomics. Collapses any run of characters outside [A-Za-z0-9_-] to a single underscore, trims leading/trailing underscores, and falls back to a literal “_” for an empty/all-punctuation input so the id is never blank.
