- 1. Do NOT use GZZ Windows. That kind of 'two-layer' window should
- NEVER (I really mean NEVER) be used. If you need to clip various drawing

- 2 If >=V39 use ScrollWindowRaster() (This one got a bug with backfill
- hooks and damage regions, but don't worry about that)
- If <V39 use ScrollRaster() or ClipBlit().

- Trond.
