Yes, and I already gave it a shot independently a few month ago but got 
lost quite early when trying to make a general interface for glCallList, 
which happens to be one of the features we will have to reimplement when 
switching to modern OpenGL API. That is why I am under the impression 
that the two goals are not completely independent.
