57<p>Sets the value of <CODE>GL_FLOAT_VEC4</CODE>-type uniform variable arrays in the vertex shader or geometry shader.</p><P>
58This function changes the values of a (<span class="argument">count</span> × 4) number of arrays. Set <span class="argument">transpose</span> to <CODE>GL_TRUE</CODE> when taking the transpose. For <span class="argument">value</span>, specify an array of values to set in the uniform. Specify <span class="argument">value</span> using an array of (<span class="argument">count</span> × 16) <CODE>GLfloat</CODE> values.
