* Do_NewWindowFromAPI(outWindow)
*
* Purpose: called to create a new window using only API calls fron MacWindows.h, Controls.h, and HIView.h
*
* Notes: called by Do_NewWindow()
*
* Inputs: outWindow - if not NULL, the address where to return the WindowRef
* - if not NULL, the callee will have to ShowWindow
*
* Returns: OSStatus - error code (0 == no error)
