10 * Things added by AROS, which needs to be kept when merging with newer MorphOS releases:
11 *
12 * 1. Explicit library bases
13 * 2. FireScreenNotifyMessage() calls
14 * 3. AddResourceToList() call
15 * 4. Decoration calls (see intuition_customize.h)
16 * 5. Hardcoded initial color table is not used and removed.
17 * AmigaOS-compatible palette is used instead.
18 * 6. Other placed marked by 'AROS:' in comments.
19 * 7. Check #ifdef's. Some of them were rearranged or completely deleted.
20 * We reuse MorphOS skin code where appropriate.
