BestSize and any user specified Min size hints. Put it to use with wxADJUST_MINSIZE, which now has a chance of working; a) if the item gets smaller, and b) with controls (like wxButton) for whom BestSize and the user MinSize share only the most tenuous relationship. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_2_4_BRANCH@17749 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
