Yes, redirecting the output to the output page will work fine as long as you're working with a "console" app. Unfortunately there are times that to initialize some of the libraries we need to create a DirectX surface, or at least a Window instance. In that case, we have to create a Win32 app, and std::out is not piped correctly to the output. I'll have to double-check this.
Where is it piped to then?
One thing is for sure though, having control over main() is very important. Otherwise it might not even be possible to create anything other than a regular console app. I thought it would be relatively trivial to take over main, but then I realized that main() is part of the library right now, so the ony way to provide your own would be modifying the source code of the library and recompiling.
Yes. Right now it's not possible to use framework as it is with WinMain (at lease that what I think). We may need to create another component usable for such cases. Gennadiy
