*
* Differences from Tk_MakeWindowExist.
*
* 1. This is always a "busy" window. There's never a platform-specific
* class procedure to execute.
*
* 2. The window is transparent and never will have children, so
* colormap information is irrelevant.
*
* Results:
* None.
*
* Side effects:
* When the procedure returns, the internal window associated with tkwin
* is guaranteed to exist. This may require the window's ancestors to be
* created too.
