* glMapBuffer maps a gl vertex buffer buffer to a ByteBuffer. The oldBuffer argument can be

* map on the same buffer mapped_buffer = glMapBuffer(..., ..., ..., mapped_buffer);

*
|
|
* @param size The size of the buffer area.
|
|
* @param oldBuffer A ByteBuffer. If this argument points to the same address as the new mapping,

* it will be returned and no new buffer will be created. In that case, size is

* ignored.
