-// there are two possible ways to create the radio buttons: either as children
-// of the radiobox or as siblings of it - allow playing with both variants for
-// now, eventually we will choose the best one for our purposes
-//
-// two main problems are the keyboard navigation inside the radiobox (arrows
-// should switch between buttons, not pass focus to the next control) and the
-// tooltips - a tooltip is associated with the radiobox itself, not the
-// children...
-//
-// the problems with setting this to 1:
-// a) Alt-<mnemonic of radiobox> isn't handled properly by IsDialogMessage()
-//    because it sets focus to the next control accepting it which is not a
-//    radio button but a radiobox sibling in this case - the only solution to
-//    this would be to handle Alt-<mnemonic> ourselves
-// b) the problems with setting radiobox colours under Win98/2K were reported
-//    but I couldn't reproduce it so I have no idea about what causes it
-//
-// the problems with setting this to 0:
-// a) the tooltips are not shown for the radiobox - possible solution: make
-//    TTM_WINDOWFROMPOS handling code in msw/tooltip.cpp work (easier said than
-//    done because I don't know why it doesn't work)
