This patch corrects the miscalculation in point unit conversion, ensuring correct margin updates. Previously, non-pt units were rounded to two decimal places. When converting back to pt, rounding was to zero decimals, making the result always less than the original. This could result in margins falling below the minimum allowed. Example: original_points = 8.4 multiplier = 2.83464566929 mm: qRound(8.4 / multiplier * 100) / 100 = 2.96 new_points: qRound(2.96 * multiplier) = 8 // wrong! The fix rounds back-converted values up to two decimals, ensuring they are never less than the original and thus stay above minimum margins. new_points: qCeil(2.96 * multiplier * 100) / 100 = 8.4 Also, remove unused function qt_convertPoint.
