Hello again

Well on Saturday I finally found some free time and got hold of a Platform SDK
and started writing up a wia.h for Wine, only to discover that IWiaDevMgr (1)
needs numerous other interfaces, and (2) is hosted in an out of process COM
server.

Now (1) would just be more work, but (2) makes the entire wia.h useless, since
both wia.h and the inter-process marshaling code needs to be generated by widl
(Wine's "midl") from a wia.idl, something I've never done before :-).

After starting on wia.idl, I noticed the interfaces just needed more and more
other interfaces, and a few nights later I gave up on that approach too,
because I realized that if IWiaDevMgr is just a stub, the other interfaces can
be empty, since they'll never be used.

So now I'm busy compiling Wine with the second wia.idl and next I'll have to
try make sti.dll play along as a proxy like it does on Windows and marshal to
some WIA DLL that is hosted by svchost.exe on Windows (AFAIK only 1 other Wine
DLL does that, eek!). Then, which is hopefully tomorrow or soon after, I can
send you a patch for testing.
