CSB loader - texture matrix bug?

Had some problems maintaining scaled texture mapping (by using texture
matrix), reading CSB into performer (or pfconv). The result was badly
sized mapping of the texture.

Added one row in pfcsb.C, in function load_appearance_bitmask64, and I'm
much more happy:

The current code section:

    if (local.texTransform)
    {
        pfMatrix *tex_transform;
        tex_transform = (pfMatrix *)pfMalloc(sizeof(pfMatrix), csb->arena);
        tex_transform->set(a.tex_transform);
        app->setAttr(PFSTATE_TEXMAT, tex_transform);
    }

Now looks like:

    if (local.texTransform)
    {
        pfMatrix *tex_transform;
        tex_transform = (pfMatrix *)pfMalloc(sizeof(pfMatrix), csb->arena);
        tex_transform->set(a.tex_transform);
        app->setAttr(PFSTATE_TEXMAT, tex_transform);
        app->setMode(PFSTATE_ENTEXMAT, PFTR_ON);
    }

Seems like the missing setMode simply was forgotten, I don't know...

Maybe this helps someone at some point...
