* Added calls to InvalidateBestSize where things affecting BestSize are modified. There are probably several other places where this still needs to be done... * Added wxWindowBase::GetBestFittingSize that will merge the BestSize into the MinSize, (if any) and return the result. * SetBestFittingSize will now only set the MinSize to the value that was passed to it, without merging in the BestSize git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@28010 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
