<p>Returns an unsigned integer obtained by converting the components of a two-component floating-point vector to the 16-bit floating-point representation found in the OpenGL Specification, and then packing these two 16- bit integers into a 32-bit unsigned integer. </p>
<p>The first vector component specifies the 16 least-significant bits of the result; the second component specifies the 16 most-significant bits.</p>
