It took a little getting used to, but I actually like the bottom/right parts of Rect. Makes resizing subrects fast and painless (in the sense, that you can resize it to make it go straight up, or left, without extra math involved), as well as getting the right_x and bottom_y values.
The only thing that x/y/width/height really helps with seems to be initialization, in my opinion. Too bad there's no way to just overload that in..
