- * DBE MI Procedure: miDbeWinPrivDelete
- *
- * Description:
- *
- * 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
- *
