+
+       The first step towards a math dialog controller...
+
+       * FormBaseDeprecated.h (hide): make public.
+
+       * FormMathsPanel.[Ch] (class FormMathsPanel):
+       (c-tor, build): no longer create the daughters in the c-tor. Wait
+       until build() is invoked to create and initialise them at the same time.
+       (dispatchFunc): now has an additional string argument, making it a
+       more general wrapper for LyXView::dispatch.
+       (mathDisplay, setActive): removed.
+       (daughters_): store the daughter dialogs in a map, using
+       the FL_OBJECT buttons to identify them.
+       (addDaughter, showDaughter): helper functions.
+
+       * FormMathsPanel.[Ch] (class FormMathsSub):
+       (connect, disconect): removed. No need for the daughters to tell the
+       parent that they're active; the parent knows already.
+       (isVisible): new method; wrapper for form()->visible.
+       no need to make FormMathsPanel a friend.
+
+       * FormMathsDelim.C (apply):
+       * FormMathsMatrix.C (apply):
+       use FormMathPanel::dispatchFunc() rather than LyXView::dispatch().
+
