OK, great. You will like the changes that are being checked in right
now, they improve shadow quality quite a bit.

Yeah, that's a problem. The ShadowMapViewport is a bit of a hack,
Shadows really belong in the light sources and in the scene graph.
I don't see a trivial solution. You can either (in increasing order of
difficulty) draw viewports individually (do a mgr->getNavigator
().updateCameraTransformation() and cut-n-paste from Window::render()
and Window::renderAllViewports()), or add a StereobufferBackground or
create a BufferStateChunk.
Hope it helps
Dirk
