* This is the MI function for deleting the dbeWindowPrivResType resource.
* This function is invoked indirectly by calling FreeResource() to free
* the resources associated with a DBE buffer ID. There are 5 ways that
* miDbeWinPrivDelete() can be called by FreeResource(). They are:
*
* - A DBE window is destroyed, in which case the DbeDestroyWindow()
* wrapper is invoked. The wrapper calls FreeResource() for all DBE
* buffer IDs.
*
* - miDbeAllocBackBufferName() calls FreeResource() to clean up resources
* after a buffer allocation failure.
*
* - The PositionWindow wrapper, miDbePositionWindow(), calls
* FreeResource() when it fails to create buffers of the new size.
* FreeResource() is called for all DBE buffer IDs.
*
* - FreeClientResources() calls FreeResource() when a client dies or the
* the server resets.
*
* When FreeResource() is called for a DBE buffer ID, the delete function
* for the only other type of DBE resource, dbeDrawableResType, is also
* invoked. This delete function (DbeDrawableDelete) is a NOOP to make
* resource deletion easier. It is not guaranteed which delete function is
* called first. Hence, we will let miDbeWinPrivDelete() free all DBE
* resources.
*
* This function deletes/frees the following stuff associated with
* the window private:
*
* - the ID node in the ID list representing the passed in ID.
*
* In addition, pDbeWindowPriv->nBufferIDs is decremented.
*
* If this function is called for the last/only buffer ID for a window,
* these are additionally deleted/freed:
*
* - the front and back pixmaps
* - the window priv itself
