A drawing whose shapes are described in the origin format's own legacy vector markup rather
than through movables.
Remarks
A carrier, not a concept: what a spreadsheet keeps out of its main drawing — the box a note is
displayed in, a form control's shape, and the pictures placed in a header or footer — held as
one unit and put back on save, so a document that has them survives a round trip. Each piece
folds into its own model as that lands (the note's box onto the note, the control's shape onto
the control, the pictures onto the print header), and the carrier goes with the last of them.
The markup is opaque: it is held as it was read and replayed unchanged, which also means the
positions in it do not follow rows and columns that are inserted or deleted. Its images are
carried by IResource id, each under the id the markup references it by.
