code: public void setIntArray(String key, int val[])

docs: Set the value for an integer vector uniform.
  <p>
  @param key name of uniform to set.
  @param val integer array with new data. The size of the array must be
  at least as large as the uniform being updated.
  @throws IllegalArgumentException if key is not in uniform descriptor or array is wrong length.
