Yes. MSODRAWINGGROUP is in several MS Office products. That's what the 45
classes are about. I can manipulate MSODRAWINGGROUP (the structure) with
these classes.

I am not yet to the point of being able to read or write this structure from
MSODRAWING[xxx] Biff records in Excel. That's because of the way
MSODRAWING[xxx] (the structure) is split into many MSODRAWING[xxx] Biff
records. And the architecture of HSSF looks only at the Biff records.

By the way, I implanted the 45 classes to be able to manipulate
MSODRAWINGGROUP from another product. Namely Microsoft Project. The 45
classes are in a separate package, which I currently call
'org.apache.poi.hdwgf' (Horrible Drawing Format)

Don't yet know where these sources will go. If someone yells at me for using
'apache' - Well. I got Eclipse and its easy enough to refactor.

FWIW, the MSODRAWINGGROUP records are used across all Office products,
especially in Powerpoint (where each slide is essentially one big
drawing), so you may want to handle this at a higher level.
