/**
 * <p>{@code glBufferSubData} redefines some or all of the data store for the buffer object currently bound to
 * {@code target}. Data starting at byte offset {@code offset} and extending for {@code size} bytes is copied to the
 * data store from the memory pointed to by {@code data}. An error is thrown if {@code offset} and {@code size}
 * together define a range beyond the bounds of the buffer object's data store.</p>
 *
 * <p>{@link #GL_INVALID_ENUM} is generated if target is not {@link #GL_ARRAY_BUFFER} or {@link
 * #GL_ELEMENT_ARRAY_BUFFER}.</p>// ww w . j ava  2 s.  c  om
 *
 * <p>{@link #GL_INVALID_VALUE} is generated if offset or size is negative, or if together they define a region of
 * memory that extends beyond the buffer object's allocated data store.</p>
 *
 * <p>{@link #GL_INVALID_OPERATION} is generated if the reserved buffer object name 0 is bound to target.</p>
 *
 * @param target Specifies the target buffer object. The symbolic constant must be {@link #GL_ARRAY_BUFFER} or
 *               {@link #GL_ELEMENT_ARRAY_BUFFER}.
 * @param offset Specifies the offset into the buffer object's data store where data replacement will begin,
 *               measured in bytes.
 * @param size   Specifies the size in bytes of the data store region being replaced.
 * @param data   Specifies the new data that will be copied into the data store.
