Our open colorwheel (ReAction class): 2 calls with the same LVOs and registers as AmigaOS 3.2's, checked against the NDK 3.2 .fd file.
colorwheel.gadget's jump table, as OpenColorWheel builds it: LVO, call, registers. build-amiga.sh (with ../../common/check_fd.py) checks this against the NDK 3.2 colorwheel_lib.fd in the stove and stops on any difference. There is no COLORWHEEL_GetClass: the class is made by name. ConvertHSBToRGB and ConvertRGBToHSB are pure (OPEN_LIBRARIES.md, section 5): arithmetic on the caller's structures, any task, any core.
| LVO | Call | Registers | Notes |
|---|---|---|---|
| -30 | ConvertHSBToRGB | a0, a1 | |
| -36 | ConvertRGBToHSB | a0, a1 |
