// Class : GeomVertexData
// Description : This defines the actual numeric vertex data stored in
// a Geom, in the structure defined by a particular
// GeomVertexFormat object.
//
// The data consists of one or more arrays, each of
// which in turn consists of a series of rows, one per
// vertex. All arrays should have the same number of
// rows; each vertex is defined by the column data from
// a particular row across all arrays.
//
// Often, there will be only one array per Geom, and the
// various columns defined in the GeomVertexFormat will
// be interleaved within that array. However, it is
// also possible to have multiple different arrays, with
// a certain subset of the total columns defined in each
// array.
//
// However the data is distributed, the effect is of a
// single table of vertices, where each vertex is
// represented by one row of the table.
//
// In general, application code should not attempt to
// directly manipulate the vertex data through this
// structure; instead, use the GeomVertexReader,
// GeomVertexWriter, and GeomVertexRewriter objects to
// read and write vertex data at a high level.
