MWG RegionInfo vs Rotation (info + sample photos)

[sebutzu]

Anyone knows if in MWG RegionInfo the AppliedToDimensions, and the X, Y, W, H are related to the image before Rotation, or after?
It seems to be before rotation, but I am not sure.
Does anyone has some sample photos that have MWG RegionInfo data, and have different rotations?
Any apps that are known to use the MWG Standard in the right way?
Thanks!

The old Google Picasa and Photools Imatch both write it correctly, or at least seem too because the resulting files showed up correctly in both of them. I would guess Lightroom and DigiKam also write it correctly.

Here are a couple images, with and without rotation, with embedded regions.
