I am curious if you have deciphered the meaning of the 0x5d BIFF record that
occurs between MSODRAWING records. It does not seem to be an anchor. If you
know, I would appreciate comments.
Here is an example from my enhanced version of BiffViewer.

The Client Anchor Atom above is the anchor which describes how the drawing
is positioned, and is interpreted outside of the Escher object. The 0x5d
record follows immediately, and I haven't got a clue about how to build it.
Also, how does your library deal with the MSODRAWING records, which are
scattered throughout the worksheet? Neither MSODRAWING nor MSODRAWINGGROUP
uses CONTINUE records like the rest of Excel.
I too had (actually have) a package that does drawings. The drawing part
(contents of MSODRAWING and MSODRAWINGGROUP records) are completely worked
out, except for these unknown BIF records, and the compression of BLIP
structures. I can build the Escher side of the MSODRAWING structure with
various kinds of shapes and properties, including PNG images (uncompressed).
However, I also cannot release just yet. I'm not even a committer. And I
thought the committers were about to release something, so I stopped work on
the Excel interface. My main interest was getting it to work with Microsoft
Project.

Well I have some code which almost goes as far as letting you do this that
unfortunately I can't release it yet.
