glBindSampler — bind a named sampler to a texturing target
| void glBindSampler( | GLuint unit, | 
| GLuint sampler ); | 
unitSpecifies the index of the texture unit to which the sampler is bound.
samplerSpecifies the name of a sampler.
            glBindSampler binds sampler to the texture unit at index unit.
            sampler must be zero or the name of a sampler object previously returned from a call to
            glGenSamplers. unit must be less than the value
            of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
        
When a sampler object is bound to a texture unit, its state supersedes that of the texture object bound to that texture unit. If the sampler name zero is bound to a texture unit, the currently bound texture's sampler state becomes active. A single sampler object may be bound to multiple texture units simultaneously.
            GL_INVALID_VALUE is generated if unit is greater than or equal to the value of
            GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
        
            GL_INVALID_OPERATION is generated if sampler is not zero or a name previously
            returned from a call to glGenSamplers, or if such a name has
            been deleted by a call to glDeleteSamplers.
