Alan, is this specified somewhere in a spec? I can't find a
description of this behaviour and we don't do this for texture objects
or buffer objects, etc.
I can't see it specifically mentioned, apart from the note that when
deleting the sampler object it should be unbound from the texture unit,
and I did consider the case of buffer & texture objects whether to do
this there too.
But getting the GL_SAMPLER_BINDING id when switching contexts and
attempting to re-bind with glBindSampler() gives a GL error, which seems
wrong to me.
I checked with the NVIDIA driver and no GL error is generated.
Alan.
