- * 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.
- * DO_TWOSTENCIL:Gross hack for two-sided stencil.
- *
- * 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 constant offset.
- * REVERSE_DEPTH: Viewport depth range reversed.
- *
- * 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.
