The list of 256 colors of the palette returned by CreateHalftonePalette should be documented. This is especially because some pages on Microsoft Learn may refer to this "halftone palette", such as:

• https://learn.microsoft.com/en-us/cpp/windows/creating-an-icon-or-other-image-image-editor-for-icons?view=msvc-170
• https://learn.microsoft.com/en-us/previous-versions/ms997621(v=msdn.10).

I post this issue here because the sdk-api repository doesn't allow for posting issues, and because it relates to Windows application development.
