resolves #15786

Changes

Made documentation for this flag more complete by noting that it tells imread() to ignore the image's EXIF orientation. If anyone has suggestions about how to phrase this better, I will be glad to update this PR.

It also seems to not scale to 8bpp if input was e.g. 16bpp.
