I did change RenderStage so that it used a new
osg::State::glDrawBuffers(..) + State::glReadBuffers(..) that does
lazy state updating for these GL state variables to avoid calling GL
when not necessary.  If there is any third party code that calls
glDrawBuffers/glReadBuffers but the OSG doesn't know about I guess
this could introduce problems.

During this dev work I did accidentally check-in a "cleaned up"
implementation of osg::State::glDrawBuffers(..) that called itself
rather than ::glDrawBuffers(), this caused a infinite loop.  I fixed
this yesterday so git master should be fine now.

W.r..t setting Read/Draw buffers to GL_BACK, this should only be
required for top level/viewer Camera's.

I can look into the issue if you reproduce the problem with an
existing OSG example let me know I'll try to reproduce the issue.  It
might also be worth you trying a clean check out of the OSG to see if
that changes what happens.

Robert.
