I fixed the cross hair cursor in svn r2326.

This may be difficult problem to fix. Historically, Kicad coordinate
math tended to truncate the floating point value rather than round it.
This may have produced a more visually pleasing rendering but rounding
is more technically accurate. I will dig around the pad coordinate code
and see if I can figure out where the problem is occurring when I get
some time.

No problem. Given the extent of the changes, I expected there to be
some issues. Honestly, it has gone better than I expected but there may
be some more bugs lurking in there.
