Yes.

I'm not sure what you mean, it seems you are trying to think too hard
about it; just don't worry about doing +1/-1, that should never be an
issue, just compute the limits the intuitive way. If you want an x by
y rectangle, just set right = left + x and bottom = top + y and
everything will behave properly.
