we could get the method below to work on pelle's win32_test / gecko
1.9. it calls a JS function init() which is in the embedded webpage.
unfortunately when we tried to migrate this to gecko 1.8.1 (FF2), the
moment i add #include "nsIDocument.h", i get a
"fatal error C1189: #error : Cannot use internal string classes
without MOZILLA_INTERNAL_API defined. Use the frozen header
nsStringAPI.h instead."
i dont know whether this is related to gecko or something else but its
driving me up the wall :(
