The ARB_bindless_texture spec says:
"When a sampler or image uniform's value is queried via any
of the GetUniform* commands, the returned value will reflect
the most recently set value through either UniformHandle* or
Uniform1i*, converted to the requested type."
This is probably unnecessary, depending on what happens with the
previous patch.
Cheers,
Nicolai
