Sorry, I don't understand your question.

There are three kind of bitmaps:

1. standard bitmaps not overridden by user-defined bitmaps
2. standard bitmaps overridden by user-defined bitmaps
3. user-defined bitmaps

The first loop processes the bitmaps of the first kind, the second loop 
the bitmaps of the second and third kind.
