Detailed render results

Legend:
✅ The image renders correctly.
🔄 The color order is flipped. BGR instead of RGB.
❌ Does not render correct image.
🚫 Could not render / rendering error / no output.

How to read the results

This is a combined table. Showing results of both, icns and app rendering. If a cell contains only one emoji, the result is valid for both. If the cell is split up, the first emoji applies to icns rendering and the second emoji to app rendering (it is the same icns file, just put inside an app bundle).

❌/✅ means the icon cannot be rendered in a plain icns file but renders fine when used inside an .app bundle (the very same icns file!). Likewise, ✅/❌ renders standalone icns files fine but fails when bundled in an app.

Empty cells were not tested at all. E.g., for argb+mask only sizes 16, 32, 48, and 128 are relevant because no other mask-sizes exist. Early OS versions skip some keys because generating a preview gets progressively harder the older it gets. Though I did preview all keys in 10.3 and 10.4 (even if the cells are empty) and they are indeed non-rendering.
