There are some difficulties with that idea.  It is not possible to  
check renderer capabilities until after an OpenGL context has been  
created, which normally Quesa does not do until you render.  Also, it  
is possible for a machine to have multiple monitors supported by  
multiple video cards, in which case a feature might be supported on  
one monitor but not another.
