If I've understood correctly, SNORM ones are supported only with 
EXT_render_snorm so those ones I was planning to add separately. For 
RGB16 I guess we would need to query the driver. Not sure what would be 
the best way to achieve this, it seems that at least i965 relies on 
_mesa_query_internal_format_default which just says to support anything 
(is broken).
