Well, Xara have never withheld documention for this. The interface /is/
documented to exactly the same extent as the Xara guys have documentation,
which is far from great, but then when GDraw was developed it was not
developed with the intention it would be a 3rd party API. Look at
where GDrawContext etc. are documented and you'll see class wrappers
for each drawing function. As you might expect many of the calls bear
a close resemblance to the attribute system, which is pretty well
documented.

This is a problem pervading much of this project, I'm afraid.
