I believe the details of this depend on which port you're using.

For Chromium, the graphics layer is Skia, and you can get a more targeted
answer on the skia-discuss mailing list.
However, Chromium already uses the stencil buffer for some path rendering,
and we've found it to be considerably *slower* than a software
implementation in common web use cases.
