[Libreoffice] [PATCH] Decoview cleanup #9 - ImplDrawFrame

[Matteo Casalin]

Hi all,
     this should ideally be my last patch to DecoView, just to not leave 
the work incomplete. Sadly, I think this patch also needs some thorough 
review, since the underlying architecture is not so clear to me.
Apart from some recoding that should have kept the functionalities, the 
corrections are:
* Share code between draw/nodraw on window devices (this needs review
   for sure, I didn't understand clearly the conditions to be met for
   the nodraw case);
* Fix drawn FRAME_DRAW_GROUP not resizing its Rectangle;
* Avoid filtering/recreating FRAME_DRAW_MENU flag.

Ciao
Matteo
