* glMapBufferRange maps a GL buffer object range to a ByteBuffer. The old_buffer argument can be null,

* in which case a new ByteBuffer will be created, pointing to the returned memory. If old_buffer is non-null,
|
|
* it will be returned if it points to the same mapped memory and has the same capacity as the buffer object,

|
* otherwise a new ByteBuffer is created. That way, an application will normally use glMapBufferRange like this:

|
* <p/>
|
|
* ByteBuffer mapped_buffer; mapped_buffer = glMapBufferRange(..., ..., ..., ..., null); ... // Another map on the same buffer mapped_buffer = glMapBufferRange(..., ..., ..., ..., mapped_buffer);
|
|
* <p/>
|
|
* Only ByteBuffers returned from this method are to be passed as the old_buffer argument. User-created ByteBuffers cannot be reused.
|
|
* <p>
|
|
* @param old_buffer A ByteBuffer. If this argument points to the same address and has the same capacity as the new mapping, it will be returned and no new buffer will be created.
|
|
* <p>
|
|
* @return A ByteBuffer representing the mapped buffer memory.
