<code class="function">glVertexAttribDivisor</code> modifies the rate at which generic vertex attributes advance when rendering
multiple instances of primitives in a single draw call. If <em class="parameter"><code>divisor</code></em> is zero, the attribute at slot
<em class="parameter"><code>index</code></em> advances once per vertex. If <em class="parameter"><code>divisor</code></em> is non-zero, the attribute advances
once per <em class="parameter"><code>divisor</code></em> instances of the set(s) of vertices being rendered. An attribute
is referred to as instanced if its <code class="constant">GL_VERTEX_ATTRIB_ARRAY_DIVISOR</code> value is non-zero.

- <em class="parameter"><code>index</code></em> must be less than the value of <code class="constant">GL_MAX_VERTEX_ATTRIBUTES</code>.
