Previously, calling `.right()` on a `Gfx::Rect` would return the last column's coordinate still inside the rectangle, or `left + width - 1`. This is called 'endpoint inclusive' and does not make a lot of sense for `Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would return 4 as its right side. This same problem exists for `.bottom()`. This changes `Gfx::Rect` to be endpoint exclusive, which gives us the nice property that `width = right - left` and `height = bottom - top`. It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly the same. All users of `Gfx::Rect` have been updated accordingly.
