Since every vertex in the addon right now has a separate glColor* equivalent call, this approach will no longer feasible. In my mind, two things can be done: one, to specifically state that colour shading does not work for this addon; two, to implement this shading via a shader.

A fair number of the ASSERTs appear to be slightly wrong, e.g.

    ASSERT(type > 0 && type < ALLEGRO_PRIM_NUM_TYPES);
    ASSERT(idx > 0 && idx < vbuff->len);
    ASSERT(start >= end);

so you should compile in debug mode and fix those.

Attached are cmake files you can use.
