[Lazarus] Editor font disturbed after upgrading to r19705

[Bart]

@Paul:

Something else I noticed.
Can there be a relationship between this and bug
http://bugs.freepascal.org/view.php?id=13062 (IDE prints garbage on
screen)?

I ask this because I noticed that the broken version produced lots of
garbage on the screen, and after your fix, this has been reduced (not
gone though).
It seems to be a win9x issue only (so hardly anyone seems to bother).
