W32 image patch (was Re: XPM via Lisp in the toolbar)

[Jason Rumney]

Below is a patch to improve image support on MS-Windows. Hopefully it
is enough to make images with masks work in the toolbar. I currently
am unable to check this in, so if someone else with write access to
CVS and access to MS-Windows to ensure the patch applies cleanly,
compiles and works can check this in, it would be greatly appreciated.

If this patch works as well for others as it does for me, then I'll
take back what I said last week about needing to disable image
support on Windows if we start pretesting from HEAD in the near
future.
