<para>
<function>glFramebufferTextureLayer</function> operates like <citerefentry><refentrytitle>glFramebufferTexture</refentrytitle></citerefentry>,
except that only a single layer of the texture level, given by <parameter>layer</parameter>, is attached to the attachment point.
If <parameter>texture</parameter> is not zero, <parameter>layer</parameter> must be greater than or equal to zero.
<parameter>texture</parameter> must either be zero or the name of an existing three-dimensional texture, one- or two-dimensional array texture,
or multisample array texture.
