Should there be one renderer for each view?

[James W. W. <os...@jw...>]

I don't see anything in the QD3D manual saying that you can't attach 
one renderer to multiple views, although I don't think I've ever seen 
sample code that did that.  Also, the Quesa implementation of the 
interactive renderer seems to assume that it is being used for one view 
(and hence one draw context), since its instance data contains some 
OpenGL state.  Is it safe to assume that a renderer will be used by at 
most one view?
