fe works again!

[Roger Gregory <roger>]

With ravi's fixes of today the xview fe displays text again!
This is only a big deal because I was stuck on it so long, but the
fixed code will be in the merge, and the merge (at least eric's copy)
will have compiled and run at least once.

The error was in the point class, a lot of variables were declared UInt4
and some comparisons were beiung done unsigned in a rather unobvious way.
This is one of the few differences between smalltalk and C++ and one of
the reasons that I have allways iencouraged everyone to do EVERYTHING in 
IntegerVar unless there is a PRESSING need not to.  This wasted me a lot
of time.  How the hell did all those Int4s & UInt4s get in there anyway?
