Yes, I haven't had time to look at the QGraphicsView class -- if it  
helps, great. If not, no worries. As to depending on Qt-4.2, other  
parts of the Avogadro code already require this (e.g., menu  
shortcuts, the undo framework to come, etc.).

One minor nitpick -- the render engine interface should be more general:
1) It should accept render engines which render the whole Molecule at  
once (e.g., for a molecular surface). This also offers optimization  
improvements. The previous render code was faster because it created  
one gluQuadric for the entire molecule, rather than constantly  
creating/deleting for each atom and bond.

2) We'll eventually need render engines which deal with residues  
(e.g., protein ribbons, etc.)

The mouse tools code is in OK shape, but I will need to spend some  
time putting in glLoadName() for selection tool purposes. I also  
spent some time thinking about other plugin interfaces.
