825In the calender the size of the combobox for the year
826is just defined by a margin from the month combobox to
827the left border. While in wxUniv the year control can't
828show all 4 digits, in wxMsw it show almost twice as
829much. Instead the year should use it's best size and be
830left aligned to the calendar. Just in case the month in
831any language is longer than it has space in the
832calendar it is shortend.This way the year always can
833show the 4 digits.
834
835This patch relies on the fact that a combobox has a
836good best size implementation. This is not the case
837with wxMSW but I don't know why.
