* ...

* Implementation buffers all vertex, colors, normal and texture-coord elements in their respective buffers
* to be either rendered directly via {@link #glEnd(GL)} or to be added to an internal display list
* via {@link #glEnd(GL, boolean) glEnd(gl, false)} for deferred rendering via {@link #draw(GL, boolean)}.

* <p>
* If unsure whether <i>colors</i>, <i>normals</i> and <i>textures</i> will be used,
* simply add them with an expected component count.
* This implementation will only render buffers which are being filled.<br/>
* The buffer growing implementation will only grow the exceeded buffers, unused buffers are not resized.
* </p>
* <p>
* Note: Optional types, i.e. color, must be either not used or used w/ the same element count as vertex, etc.
