#i125020# fix rounding error in AquaSalGraphics::RefreshRect()
Rounding left and width down can accumulate a rounding error of almost two
in
the calculation of right. The existing code compensates for this by
increasing
the width by two, but since left has been decremented by one to accommodate
for
antialiasing artifacts this compensation is one to few by itself and two to
few
when accounting for antialiasing artifacts on the right. Y-pos and height
have
the same problems and get the matching fix.
