This one is a little tricky to explain.
Say I'm working on a canvas. And I use the rotate function to get a better angle on the pic or whatever.
Sometimes... the resulting orientation IS the final pic.
But ArtRage saves it not in a 'WYSIWYG' kinda way. It saves it as if the canvas hadn't been rotated. Which means I've got to open the pic in another app to change the orientation.
