Also note that previously the docs just said "The result is used to sample the texture at texture stage m by performing a 1D lookup." The addition of using 0.0 to extend the vector is apparently recent.

Yes, but additionally to the sampling function I needed the dimension of the vector cast, so I'd have needed a switch myself too.

shader_glsl_get_sample_function() also gives you back a mask, which you can use to determine the size.
