This data object is returned by GeomVertexArrayData::get_handle() or modify_handle().
As long as it exists, the data is locked; when the last of these destructs, the data is unlocked.
Only one thread at a time may lock the data; other threads attempting to lock the data will block. A given thread may simultaneously lock the data multiple times.
This class serves in lieu of a pair of GeomVertexArrayDataPipelineReader and GeomVertexArrayDataPipelineWriter classes

Returns a readable pointer to the beginning of the actual data stream, or NULL if the data is not currently resident.
If the data is not currently resident, this will implicitly request it to become resident soon.
If force is true, this method will never return NULL, but may block until the data is available.

Creates a context for the data on the particular GSG, if it does not already exist.
Returns the new (or old) VertexBufferContext. This assumes that the GraphicsStateGuardian is the currently active rendering context and that it is ready to accept new datas. If this is not necessarily the case, you should use prepare() instead.
Normally, this is not called directly except by the GraphicsStateGuardian; a data does not need to be explicitly prepared by the user before it may be rendered.

Returns true if the vertex data is currently resident in memory.
If this returns true, the next call to get_handle()->get_read_pointer() will probably not block. If this returns false, the vertex data will be brought back into memory shortly; try again later.
