Well, w32Edge sort of does mean 100% for width and height parameters, which
is what I'd meant it for anyway. I really didn't think it useful for the
left and top parameters. Infact, now that I think it through a bit more,
maybe we should get rid of w32AltEdge and just use w32Edge. For the left and
top parameters, it would mean the 100% of the parent sizes and for the width
and height is would 100% also. If no one complains about this, I'll get rid
of w32AltEdge constant.
