/* Template for building functions to plug into the driver interface
* of t_vb_render.c:
* ctx->Driver.QuadFunc
* ctx->Driver.TriangleFunc
* ctx->Driver.LineFunc
* ctx->Driver.PointsFunc
*
* DO_TWOSIDE: Plug back-color values from the VB into backfacing triangles,
* and restore vertices afterwards.
* DO_OFFSET: Calculate offset for triangles and adjust vertices. Restore
* vertices after rendering.
* DO_FLAT: For hardware without native flatshading, copy provoking colors
* into the other vertices. Restore after rendering.
* DO_UNFILLED: Decompose triangles to lines and points where appropriate.
*
* HAVE_RGBA: Vertices have rgba values (otherwise index values).
* HAVE_SPEC: Vertices have secondary rgba values.
*
* VERT_X(v): Alias for vertex x value.
* VERT_Y(v): Alias for vertex y value.
* VERT_Z(v): Alias for vertex z value.
* DEPTH_SCALE: Scale for offset.
*
* VERTEX: Hardware vertex type.
* GET_VERTEX(n): Retreive vertex with index n.
* AREA_IS_CCW(a): Return true if triangle with signed area a is ccw.
*
* VERT_SET_RGBA: Assign vertex rgba from VB color.
* VERT_COPY_RGBA: Copy vertex rgba another vertex.
* VERT_SAVE_RGBA: Save vertex rgba to a local variable.
* VERT_RESTORE_RGBA: Restore vertex rgba from a local variable.
* --> Similar for IND and SPEC.
*
* LOCAL_VARS(n): (At least) define local vars for save/restore rgba.
