<para>
<function>glFramebufferTextureFace</function> operates like <citerefentry><refentrytitle>glFramebufferTexture</refentrytitle></citerefentry>,
except that only a single face of a cube map texture, given by <parameter>face</parameter>, is attached to the attachment point.
<parameter>face</parameter> must be <constant>GL_TEXTURE_CUBE_MAP_POSITIVE_X</constant>, <constant>GL_TEXTURE_CUBE_MAP_POSITIVE_Y</constant>,
<constant>GL_TEXTURE_CUBE_MAP_POSITIVE_Z</constant>, <constant>GL_TEXTURE_CUBE_MAP_NEGATIVE_X</constant>, <constant>GL_TEXTURE_CUBE_MAP_NEGATIVE_Y</constant>,
or <constant>GL_TEXTURE_CUBE_MAP_NEGATIVE_Z</constant>. <parameter>texture</parameter> must either be zero, or the name of an existing cube map texture.
