That seems right.  Quesa saves the illumination style with each 
transparent primitive, but only uses it to decide whether to use 
specular highlights.  That is, it distinguishes Phong and Lambert 
illumination from each other, but does not consider NULL 
illumination.  This should probably be filed as a bug, if it hasn't 
been already.

What platform(s) are you targeting?  If all you need is Mac OS X, 
then I would suggest not doing the selection stuff inside Quesa, but 
using a transparent overlay window.  That way, the Quesa content does 
not need to be re-rendered as the selection rectangle changes.
