[Mesa-dev] [RFC PATCH 18/26] glsl: allow bindless samplers/images as vertex shader inputs

[Samuel Pitoiset]

The ARB_bindless_texture spec says:

   "Modify Section 4.3.4, Inputs, p. 34"

   "(modify third paragraph of the section to allow sampler and
    image types) ...  Vertex shader inputs can only be float,
    single-precision floating-point scalars, single-precision
    floating-point vectors, matrices, signed and unsigned integers
    and integer vectors, sampler and image types."
