State of the art for Gecko embedding in Windows?

Hey guys,

Are there any *coherent* resources that describe how it should be done
on Windows? Just init'ing XPCOM alone we have several alternatives
such as NS_InitEmbed, NS_InitXPCOM*, XRE_InitEmbedding, etc. Each of
these says the other methods are deprecated, etc.

The only "official" embedding method seems to be WinEmbed, because it
lives in the trunk. However, starting the program we see that there
are all these "unsupported" words spread all around the corners.

Adam Lock's ActiveX control is good for a quick embedding, but seems
to be seriously outdated and is also not suitable if I want some XPCOM
object iterations.

Any guidance would be much appreciated!

Cheers,
Chris
