 * Name: nxtk_rawwindow
 *
 * Description:
 *    This function is the constructor for a raw NXTWINDOW object. 
 *    This provides a one-to-one mapping with the window APIs in nx.h.
 *
 * Input Parameters:
 *   handle - The handle returned by nx_connect or nx_open
 *   cb     - Callbacks used to process window events
 *   arg    - User provided value that will be returned with NX callbacks.
 *
 * Return:
 *   Success: A non-NULL handle used with subsequent method calls
 *   Failure:  NULL is returned and errno is set appropriately
 *
