/**
* Creates a `NormalizedRect` from a region of interest and an image orientation, performing
* sanity checks on-the-fly. If the input region of interest equals `CGRectZero`, returns a default
* `NormalizedRect` covering the whole image with rotation set according `imageOrientation`. If
* `roiAllowed` is NO, an error will be returned if the input region of interest is not equal to
* sanity checks on-the-fly.
* If the input region of interest equals `CGRectZero`, returns a default `NormalizedRect` covering
* the whole image with rotation set according `imageOrientation`.
* If `roiAllowed` is NO, an error will be returned if the input region of interest is not equal to
* `CGRectZero`.
* Mirrored orientations (`UIImageOrientationUpMirrored`,`UIImageOrientationDownMirrored`,
* `UIImageOrientationLeftMirrored`,`UIImageOrientationRightMirrored`) are not supported. An error
* will be returned if `imageOrientation` is equal to any one of them.
*
* @param roi A `CGRect` specifying the region of interest. If the input region of interest equals
* `CGRectZero`, the returned `NormalizedRect` covers the whole image. Make sure that `roi` equals
* `CGRectZero` if `roiAllowed` is NO. Otherwise, an error will be returned.
* @param imageOrientation A `UIImageOrientation` indicating the rotation to be applied to the
* image. The resulting `NormalizedRect` will convert the `imageOrientation` to degrees clockwise.
* Mirrored orientations (`UIImageOrientationUpMirrored`, `UIImageOrientationDownMirrored`,
* `UIImageOrientationLeftMirrored`, `UIImageOrientationRightMirrored`) are not supported. An error
* will be returned if `imageOrientation` is equal to any one of them.
* @param roiAllowed Indicates if the `roi` field is allowed to be a value other than `CGRectZero`.
* @param error Pointer to the memory location where errors if any should be saved. If @c NULL, no
* error will be saved.
