<P>
Given a sampler and a level of detail the size (width in <I>x</I>, height in
<I>y</I>, and depth in <I>z</I>) of the corresponding texture buffer is returned
as the result of the operation.
</P>
<P>
Because texture buffers lack mipmaps, the <I>lod</I> parameter is unused.
</P>
<P>
Texture buffer samplers are created with the <B>EXT_texture_buffer_object</B>
extension. See:

Texture buffer object samplers roughly correspond to the <I>tbuffer</I>
functionality of DirectX 10.
