<para>
<function>imageStore</function> stores <parameter>data</parameter> into the texel at the coordinate <parameter>P</parameter> from
the image specified by <parameter>image</parameter>. For multi-sample stores, the sample number is given by <parameter>sample</parameter>. When
<parameter>image</parameter>, <parameter>P</parameter>, and <parameter>sample</parameter> identify a valid texel, the bits
used to represent data are converted to the format of the image unit in the manner described in of the OpenGL Specification and stored to
the specified texel.
