February 20, 2017         Version 8.0.2

         - Fixed TRSPathData.AddArcSvg method to only call AddEllipse if it

           is not an invisible point in the case where P1 = P2

-------------------------------------------------------------------

January 8, 2017           Version 8.0.1

         - Removed hack in TRSPathData.FillPath method to overcome bug in

           Embarcadero's TCanvasD2D.DoDrawPath method.  The TCanvasD2D.DoDrawPath

           bug would cause a black screen in some cases.  The hack was expensive

           in terms of performance and I finally figured out Embarcadero's bug.

           Embarcadero's bug exists as of Delphi Berlin (QC https://quality.embarcadero.com/browse/RSP-16336)

           To fix the bug, copy FMX.Canvas.D2D.pas unit to your app dir and

           in the TCanvasD2D.DoDrawPath method, change:

                 if not Closed then

                   Path.EndFigure(D2D1_FIGURE_END_OPEN);

           to:

                 if (APath.Count < 1) or (APath[APath.Count - 1].Kind <> TPathPointKind.Close) then

                   Path.EndFigure(D2D1_FIGURE_END_OPEN);

           Please see blog post for more information:

Note: This release dramatically changed support classes in order to

      better support XE4 Mobile compiler features: Automatic Reference Counting,

      TList deprecation, and suggested deprecation of Pointer type. It makes

      heavy use of generics instead of older TList-type and TGHashTable classes

                - Include RSConstants.pas

                - Changed all methods and properties that use IUnknown interface to use

                  IInterface interface.  Added IInterface interface for Delphi 5 support

                - Changed all QueryInterface calls to use Supports functions.

                - Removed reference counting code for .NET (not needed)

                - Changed ToString properties to AsString and GetToString methods to

                  ToString to sync better with .NET (in which all objects have ToString

                  method)

                - Changed Tag properties to be of TRSTag type (Win32=Integer;.NET=Variant)

                - Introduced TxxxPersistent class to get around a delphi

                  compiler bug with class helpers (QC report #11019)

                - Added inherited Creates calls to constructors for

                  compatibility with .NET

                - Deleted AfterConstruction and BeforeDestruction methods (for .NET)

                - Extracted icons from DCR files to create assembly bitmap files

                  for design-time icons in .NET

                - Conditional compiled IUnknown methods (_addref, _release...)

                  because they are not needed with .NET

        RiverSoftAVG Common Classes Library (GCollections package in Delphi 5, 6, and 7;

                               RSCommon package in Delphi 2005 (Win32) and

                               RiverSoftAVG.Common assembly in VCL.NET)

                - Created TRSEncodedBits class (in RSEncodedBits.pas), a TBits descendant

                  with methods to encode/decode simple types into the TBits

                - Modified InterfaceCollections.pas

                        - Modified TGInterfaceList to descend from TPersistent

                        - Modified descendants of TGInterfaceList to correctly override

                          methods

                        - Modified list classes to use a dynamic arrays instead of a

                          pointer to such an array (as used for Win32).  The pointer

                          implementation was left for Win32 since it is faster than the

                          dynamic array implementation

                        - Changed DEMO out of memory errors to use standard Exception,

                          instead of EOutOfMemory exception, which (contrary to help file)

                          seems to have disappeared from the SysUtils unit

                - Modified HelperFunctions.pas

                        - Added WriteStringToStream function

                        - Added SameValue and Supports functions for Delphi 5

                        - Added CreateObjectClass and ClonePersistentClass methods

                - Modified GStreams.pas

                        - Added Close method to TGBufferStream (useful for .NET)

                        - TGSpecialFiler is not available for .NET (because can't crack

                          protected methods of TReader/TWriter)

                - Modified GRegularExpression.pas

                        - Modified String references to AnsiString references (for .NET

                          compatibility).  The Regular Expression object must use

                          AnsiString (one byte characters) because it uses set operations

                          which do not work with wide chars.

                - Modified GParser.pas

                         - Changed StrScan calls to Pos, even though StrScan is faster it is not

                         .NET compatible

                - Modified GLists.pas

                         - Added TQOrderedList class, which is base class for the TQxxx

                           stacks and queues, and TQOrderedListClass type.  These classes

                           are useful because they have a virtual constructor, unlike

                           Borland's classes

                - Modified GHashtable.pas

                         - Modified TGCustomHashTable to use a dynamic array of hash

                           table entries (THashtableEntries) instead of a pointer to

                           such an array (as used for Win32).  The pointer implementation

                           was left for Win32 since it is faster than the dynamic array

                           implementation

                - Modified GGraph.pas

                         - Changed TGCustomGraph.AddNode method visibility from protected

                           to public (.NET does not like changing visiblity with methods)

                - Modified DataStructures.pas

                         - Added TFloatHeapElement, TFloatHeap, and TFloatPriorityQueue classes

                         - Changed TPriorityList.OrderedListClass to use GLists.TQOrderedList

                           instead of Borland's classes because we can't get to the items of the

                           list quickly

                - Modified Structures.pas

                         - Added overloaded AddObject method to TGStringList

                - Added RSGraphics.pas, moved from internal development package to common

                  classes library.  Modified RSGraphics.pas as well:

                         - Added RSCenterPoint functions

                         - Added DrawPieSlice procedure

                         - Added DrawArrow procedure and TArrowOption types

                         - Changed Gradient functions to accept an open array of TColor,

                           instead of TColors

                         - Moved TObjectSize from Game.pas to RSGraphics.pas

                         - Created hierarchy of TRSCustomRect, TRSObjectRect, and TObjectSize

                         - Added TRSRect, TRSPoint and functions to manipulate them

                         - Added overloaded DrawShape procedures and TRSShapeStyle type

                         - Fixed LineGradient to handle "reversed" TRects (left > Right, etc)

                         - Fixed RotateFont to change font name if font is not a true type

                           (and wouldn't thus rotate)

                         - Added GetRotatedTextExtent function (Delphi's Canvas.TextExtent

                           does not work for rotated fonts)

-------------------------------------------------------------------

March 2005    Version 3.4

        - Added RSConsts.pas and DataStructures.pas to package

-------------------------------------------------------------------

January 2005    Version 3.3

        - Modified to work with Delphi 5, 6, 7, and 2005 (Win32)

                - Added RSDefines.inc to simplify updates for new

                  versions of Delphi

                - Modified source files to use RSDefines.inc

- Renamed GCollections package to RSCommon package for Delphi 2005 ONLY

- Modified source files to work with .NET (Incomplete)

-------------------------------------------------------------------

May 2004    Version 3.2

      - Added RSGraphics and RSVector units to Common library

-------------------------------------------------------------------

March 2004    Version 3.1 (First Separated History for Common Library)

      - Added code to TGCollection and TGCollectionItem to attempt to

        mimic notifies like Delphi 6 and 7 collections

      - Added IVector interface

      - Changed ILocation interface to descend from ICloneable

      - Installation script is much smarter about managing the different Delphi versions
