drawingml
Published on crates.io as drawingml (the plain name drawing was already taken by an unrelated crate) — referred to simply as drawing inside the workspace and in every use drawing::... in the code, via a local package alias.
Shared DrawingML content model — shape geometry, transforms, fills, colors, lines, visual effects, and text bodies (paragraphs/runs/bullets) — factored out once and reused by word-ooxml, excel-ooxml, powerpoint-ooxml, and chart instead of being duplicated three times over.
Builds on xml-core (low-level XML) only.
Models a shape's content only — CT_ShapeProperties, the type behind <a:spPr> wherever it appears (position/size via Transform2D, outline via Geometry, interior paint via Fill/Color, stroke via Line, effects via EffectList) — never a shape's anchor/container, since how a shape is placed within its host document (xdr:twoCellAnchor for Excel, wp:inline/wp:anchor for Word, direct placement in p:spTree for PowerPoint) is structurally different per format and stays each host crate's own responsibility.
Part of the office-toolkit workspace — see that repository's docs/Architecture.md for how this crate fits into the rest of the stack.
