Does the orientation flip.c settled on swap the axes?

Asked of the SIZE FOLD, not of the EXIF tag: a raw's recorded orientation is not always right, and iop/flip.c exists precisely so the user can override it. Its _flip_resolve() merges the two, and what this reads – the rect flip's own fold maps its input to – is the consequence of that merge. So a corrected orientation is honoured with no access to flip's private data and no second copy of the merge rule.

Read from flip's record on the GUI side and from flip's piece on a pipe, which are the same fold run by the two sides; nothing else in the pipe transposes. The focused-module exception cannot disturb it either: flip is tagged IOP_TAG_DISTORT and no module's operation_tags_filter() suppresses that tag – crop filters DECORATION, ashift DECORATION|CLIPPING.

A disabled flip folds its input to itself, so the answer is FALSE, which is what an orientation of NONE means. A square frame cannot express a swap, and does not need to: the canvas has the same dimensions either way.
