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().
