Multiple inheritance is not needed...many languages don't have it, but 
use other mechanisms.
Anyway, you're missing a branch:
object
    solid
    patch
    aggregate (CSG objects...not necessarily solid. Meshes are still 
patch objects.)

Things like global_settings, the camera, light sources, etc. would need 
modification to fit in this heirarchy, of course...that's if you want 
that. "object" could have the meaning of a language object instead of a 
shape.

object
    global_settings
    transformable_object
        texture, ...
        camera
        light_source
        shape
            solid, patch, aggregate...

Many of these would never be seen by the user, they would only exist to 
help categorize things.
