Dominik StrebelandClaude Opus 5.5 aece097096 Render: a picture's fill shows behind its transparent pixels ...

PowerPoint draws a picture's own fill (p:pic/p:spPr) behind the picture, so
it shows through its transparent pixels: a synthetic deck with one
half-transparent PNG three times (no fill, an orange fill, a yellow fill
with a blue outline), exported as PDF, shows the orange and yellow boxes
behind the image. DeckCraft drew the outline but never the fill.

Old equation objects use this: an OLE object (p:oleObj, Equation.3) has a
fallback picture whose spPr gives it a coloured box behind the equation's
transparent metafile. The reader took only the picture's image as the
object's preview and dropped its fill and line.

- The shape-fill loop moves into Renderer::fill_geometry; a picture and an
  embedded object's preview paint their own explicit fill with it before
  the image (a style fill alone still draws nothing, as before).
- An embedded object without a fill or line of its own takes them from
  its fallback picture's spPr; its frame keeps its own position.
