My thoughts on how to do it were more of a hack than a proper implementation. I
would not recommend it as a sustainable solution. 

The proper way to do it I think is as outlined.  However, this is not very low
hanging fruit and will require a lot of work.  There are a lot of
interdependencies and I thought an incremental approach would not work, but I'm
happy if I'm wrong.

Note that I tried to get tests included.  The biggest issue here is not the
tests, it is that the ITextServices and ITextHost assume the use of the
thiscall calling convention, even in C (!!).  Check the patches sent by me to
wine-patches earlier this year on how I thought it might be done.  However, the
goalposts kept moving on me and then I ran out of holiday time :(.  

I was able to make a trivial ITextHost implementation.  Again, written with
hack like purposes in mind.

If someone could get unittests in (even if it only contains a test of one call)
that cover the thiscall stuff then this would be good and a full test suite
could be written and things can move forward fairly rapidly.  This first step
probably requires quite a bit of thinking but not much code.
