/**

|
* This object provides the functionality of both a GeomVertexReader and a
|
||
|
|
* GeomVertexWriter, combined together into one convenient package. It is
|
||
|
|
* designed for making a single pass over a GeomVertexData object, modifying
|
||
|
|
* rows as it goes.
|
||
|
|
*
|
||
|
|
* Although it doesn't provide any real performance benefit over using a
|
||
|
|
* separate reader and writer on the same data, it should probably be used in
|
||
|
|
* preference to a separate reader and writer, because it makes an effort to
|
||
|
|
* manage the reference counts properly between the reader and the writer to
|
||
|
|
* avoid accidentally dereferencing either array while recopying.
