Yes, that's one way to do it - store a reference to the texture object
within the TriMesh's attribute set as a whole.

The other way to do it is to put both the texture and the TriMesh in the
same group.

A group acts as a kind of "scope delimiter" for the state changes within
it, so that if you have:

    Group1
        TriMesh1
        Group2
            TextureA
            TriMesh2
            TriMesh3
        Group3
            TextureB
            TriMesh4

Then TriMesh 1 will be rendered without a exture, TriMesh2 and 3 will
have TextureA, and TriMesh4 will have TextureB.

If a TriMesh has a texture in its own attribute set, that overrides the
"current" (=3D=3Dlast processed texture in the current group or a parent
group) texture - if it doesn't, it's drawn in the current texture if
any.
