[REVIEW][3-5] fdo#38635: sw: printing border lines gaps regression

[Michael Stahl]

proposing for libreoffice-3-5:

with the old border painting code, there is a special case for printing
where the vertical borders are shortened so they don't overlap with the
horizontal borders (the old borders were rectangular).  this seems to be
completely unnecessary and detrimental with the new way the corners are
painted (slanted), and causes huge gaps in the corners.

with the fix the huge gap is removed, but sometimes a very small gap
remains, which probably means the start/end points of the borders are a
little bit off and requires further investigation.
