Almost; a group of samplers will have exactly the same *group* of
resources, but in this example I can not know which *kind* (2D, 3D, ...)
of resource is accessed.

Right, I merely intended to mention that something has to be changed in
TGSI to make the information available.
(This is somewhat similar to using the Dimension index with
TGSI_FILE_TEMPORARY_ARRAY to separate TEMP arrays).
