The ARB_bindless_texture spec says:
"Replace Section 4.1.7 (Samplers), p. 25"
"Samplers can be used as l-values, so can be assigned into and
used as "out" and "inout" function parameters."
"Replace Section 4.1.X, (Images)"
"Images can be used as l-values, so can be assigned into and
used as "out" and "inout" function parameters."
