glsl: reject bindless samplers/images frag inputs without 'flat'
From section 4.3.4 of the ARB_bindless_texture spec "(modify last paragraph, p. 35, allowing samplers and images as fragment shader inputs) ... Fragment inputs can only be signed and unsigned integers and integer vectors, floating point scalars, floating-point vectors, matrices, sampler and image types, or arrays or structures of these. Fragment shader inputs that are signed or unsigned integers, integer vectors, or any double-precision floating- point type, or any sampler or image type must be qualified with the interpolation qualifier "flat"." v3: - update spec comment formatting Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-by: Timothy Arceri <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]>
