NV_register_combiners can easily do a dot product "tex0 dot tex1", and put this into the r, g and b components of spare0, for example. This is similar to the DOT3_RGB texture env mode.
Does anyone know how, in a single general combiner, to do the dot product and save the results into all 4 r, g, b AND A components of the destination register? i.e. can I do a "DOT3_RGBA" in a single general combiner?
