14 When a sampler object is bound to a texture unit, its state supersedes that of
15 the texture object bound to that texture unit. If the sampler name zero is bound to
16 a texture unit, the currently bound texture's sampler state becomes active. A single
17 sampler object may be bound to multiple texture units simultaneously.
