It's a lot like 3D in that you wireframe construction. Which is why things appear better in a single raster image as opposed to a layered, stacked, working file. It's only upon output that the app can 'bake in' any such visual helpers. will sacrifice some anti-aliasing and sub-pixel rendering for the ability to edit the content. InDesign, Photoshop, Illustrator, GIMP, Inkscape, or anything else. I think this is a case of 'can't see the forrest because of all the trees.'
