In principle, the current Svg/Emf/Wmf and PDF handling is trying to achieve the same thing: Keep the original stream untouched, provide a replacement graphics, and a kind of rendering. To hold the data, the Svg/Emf/Wmf and PDF were using different structures though. This commit consolidatates that, and makes the Insert -> Image... (for PDF) actually using the VectorGraphicData to hold the original stream. This breaks loading the PDF as a document via PDFium - I'll fix it in the next commit(s).
