Short Description: Qt4 Accounting View: Basic "Account Row Graphics Item"
Bug Number: n/a
Release notes (y/n): no, not yet.
For Release Nums: 6.1

(1) Added "Account Row Graphics Item" QGraphicsItem class (stub), as a
 conditionally managed child item in SimObjGfxItem.

(2) Removed old-style SimObjGfxItem custom-drawing methods. There is still
 a little custom drawing, e.g. to implement an opaque background.  But the 
 major features are implemented with child QGraphicsItems.

--------------------------------
QtUtils/AcctRowGfxItem.hpp  -- NEW
QtUtils/AcctRowGfxItem.cpp  -- NEW
QtUtils/Make.package
QtUtils/QtUtils.pro
QtUtils/QtUtils.vcproj
QtUtils/QtUtilsGenerated.pro
QtUtils/QtUtilsGenerated.vcproj
--------------------------------

Added "Account Row Graphics Item" QGraphicsItem class to encapsulate 
and manage the row of Account and Aggregate-Account Graphics Items in 
a Simulation Object "Region" Item in the new Qt4 GraphicsView-based 
Accounting Workspace.

This initial "stub" implementation just shows "AcctRowGfxItem" as a test
string (implemented as a child QGraphicsTextItem).

Other features:
  (1) Receives SimObj Callbacks via the parent SimObjGfxItem.
  (2) Implements also QObject, at least for the parent to receive the
      QObject "destroyed" signal. 

-------------------------
QtUtils/SimObjGfxItem.hpp
QtUtils/SimObjGfxItem.cpp
-------------------------

(1) Removed old implementation of custom drawn (rather than "composited") 
 SimObj Icon and SimObj Name Label, as it has become effectively dead
 code AND because the "composition" approach now has excellent performance
 (in the newest versions of Qt, i.e. beyond Qt 4.4).

 REMOVED:
   bool useCompositeGfxItems() const;

   // Two implementations of painting: (1) without, (2) with child items 
   void paint_custom (QPainter*, const QStyleOptionGraphicsItem*, QWidget*);
   void paint_composite (QPainter*, const QStyleOptionGraphicsItem*, QWidget*);
   .. this implementation moved directly to the QGraphicsItem virtual paint 
   .. method: void paint (QPainter*, const QStyleOptionGraphicsItem*, ..)

(2) When in an Accounting Workspace (see bool onAccountingCanvas()), manage 
 a AcctRowGfxItem ("Account Row Graphics Item") instance below the SimObj
 Icon and SimObj Name Label.

 ADDED:
   AcctRowGfxItem* _acctRowItem;
   void updateAcctRowGfxItem (bool showSelected=false);
   void acctRowItemDestroyed (QObject*);  // private Qt slot

(3) Unhandled SimObj callbacks are passed to the AcctRowGfxItem, if that
  QGraphicItem is instantiated (i.e. only in the Accounting View).

-----------------------------
QtUtils/WorkspaceGfxScene.hpp
QtUtils/WorkspaceGfxScene.cpp
-----------------------------

Removed method:
  bool useCompositeGfxItems() const;

In method: WorkspaceGfxScene::layoutNetwork(), show message box:
  "Layout Network operation is not implemented in this view."
