The window shouldn't matter if you're using a Pixmap or pBuffer
(that's largely the point of using them).

Does this actually cause any problems for subsequent use of NVIZ?
When the zoom code completes, there shouldn't be a current context or
current drawable; the window's expose handler should re-instate them
If this causes a problem, we could probably restore them.
