Disallow operations on structs containing samplers ESSL 1.00 spec section 5.9 says that equality operators don't operate on structs containing sampler types. Section 5.7 also suggests this. ESSL 3.00 doesn't have a similar restriction. ESSL 1.00 spec section 4.1.7 says that structs containing samplers can't be used as l-values. This is interpreted to apply also in the case of ESSL 3.00, which similarly disallows samplers as l-values, but doesn't explicitly mention structs.
