Looks buggy indeed - for texture opcodes it tries to subtract the shadow coord
from dimension for dim_layer however the value from
tgsi_util_get_texture_coord_dim() never includes that in the first place. And
therefore dim_layer_shadow (which is used to determine the mask in this case)
would be wrong too (just XY instead of XYZ for 2d shadow texture).</pre>
