Added members “function Invalidated(const aBounds: TSVGRect): Boolean;” “procedure InvalidateRect(const aRect: TSVGRect);” and “property UpdateRectList: TList read GetUpdateRectList;” to TSVGRoot. These can be used to restrict rendering to the supplied rectangles for efficiency.
Added “rsCalcCache” to the TSVGRenderMode. When this is included in the TSVGRoot.RenderMode then only the element cache will be recalculated, no actual painting will take place.
Fixed a bug which caused TSVGPathData.Count to be inconsistent. It will now return the TSVGPathPoint count, including M and Z.
Fixed a bug in TSVGPathDataD2D.AddPathData which caused figures not be closed if open and closed figures where both present in a geometry
Fixed a bug which caused animated elements not being updated if sroPersistentBuffers was included in the TSVGRoot.RenderOptions.

Fixed bug: On FMX the element bounds were not calculated correctly, which caused mousepointer events not being fired.
Fixed bug: When Direct2D and GDI+ render contexts are both enabled, this causes an error when Direct2D is not available on the system. Fixed this by adding “delayed” to the external function declarations.
Fixed some bugs in the rendering procedures.

Fixed a SVG control sizing problem in the FPC/Lazarus SVGViewer application
Version 2.3 update 4, 22-2-2020
Important!
In this update the SVG components and controls are upgraded. This means that some properties are added or deleted or changed, which will give warnings when you update the SVG control packages and then open your project in the Delphi or Lazarus IDE. You should therefore make a backup of your application source including your previous version of the SVG package before upgrading.
In principle all warnings about changed properties should be accepted. When you have used the FMX (Firemonkey) version of the TSVG2ImageList from version XE8 onwards, the SVG info will be lost and you have to import the SVG’s again after upgrading. The TSVG2ImageList for VCL and FPC/Lazarus will give warnings but will be o.k. if you accept all warnings.
Other changes:
Fixed an error in the TSVGBaseBitmap.CopyFrom method. The destination rectangle was not calculated correctly which resulted in an incomplete copy.
Fixed a problem in font selection. Sometimes text was not displayed because the font was not found locally on the system. Now more fall back fonts are defined for Windows, OsX and Linus platforms.
Fixed an error in the lighting filters which caused an exception on freeing the root.
Fixed an error in the box-blur algorithm that could cause an exception.
Version 2.3 update 3, 8-12-2019
Fixed problem with embedded raster graphics if the type (png, bmp etc.) is not explicitly mentioned in the mime type. The package will attempt to determine the type from the raw data.
Fixed a problem with temporary bitmaps of zero size in Direct2D and Aggpas render context which threw exception errors.
Fixed an error with anchoring text on a path.
Fixed an error with calculating the source graphic rectangle for SVG graphics with filters.
Fixed an error with calculating the bounding rectangle for non outer SVG elements.
Version 2.3 update 2, 31-10-2019
– Fixed error “Object state out of sync”. This happened if the DOM structure state changed between rendering. The fix is that the ObjectStateTree is invalidated (ObjectStateInvalid = TRUE) if an element is added or deleted or a href attribute is changed. ObjectStateInvalid = TRUE will cause a rebuild of the ObjectStateTree on the next rendering if sroEvents is included in the options.
– Fixed error with DPI scaling for render context Direct2D and GDI+. If the monitor is set on a higher DPI scale before the applications was started the SVG image was rendered too big. Reason was an incorrect DPI setting for these render contexts which caused a doubling of the scale.
– Fixed an cause for a compiler error in XE2 (URW1147 caused by a call to Finalyze on a TBytes object) in BVE.SVG2FontGDI.pas
Version 2.3 update 1, 21-9-2019

New license terms for licenses bought after 1-8-2018
Version 2.2 update 11, 24-6-2018
Added “AspectRatioAlign” and “AspectRatioMeetOrSlice” properties on the SVG controls. Together with the “AuotViewbox” property these control the aspect ratio of the SVG graphic within the control.
Added support for the “fill-rule” and “clip-rule” presentational attributes. This is supported by Direct2D and Aggpas render contexts, but not by the FMX render context and the GDi+ render context.
Added support for decimal and hexadecimal entity parsing in BVE.SVG2XMLReader.pas
Added support for downloading external resources from internet, this must be enabled by define “InternetAccess” in CompilerSettings.inc
Improved parsing speed of path elements with about 30%
Changed implementation of ISVGRenderBuffer for improved support for bitmap operations on rotated elements
Changed bitmap buffers for BVE.SVG2Control.FMX.pas, BVE.SVG2Image.FMX.pas to support screen scale other than 1 (iOS)
Changed behaviour of unsupported float values (null) of element parameters in BVE.SVG2SaxParser.pas and BVE.SVG2PathData.pas, in case of an unsupported value the default value of the attribute will be used.
Fixes a bug on the FMX controls, opacity property was broken
Fixed a bug in SVGControl (VCL and FMX) that caused an access violation if the bitmap buffer is zero size due to clipping.
Fixed a bug “bus error” on Android, caused by “packed” directive on the TSVGPathPoint record
Fixed a bug which could cause an access violation on the specular light filter, because of bitmap buffer size mismatch
Fixed a bug which could cause clipPaths not being rendered correctly in case of nested clipPaths
Fixed a bug which caused opacity attribute not being rendered correctly on gradients by Aggpas render context.
Version 2.2 update 10, 4-4-2018
Fixed bug: Internal search on element id was case-insensitive.
Fixed bug: Opacity was applied double on radial and linear gradient in the render context implementation for Direct2D
Fixed bug: Temporary bitmap buffers where not always pixel aligned with target bitmap, which resulted in color shift on edges of for example clippath.
Version 2.2 update 9, 30-1-2018
Fixed a bug that could lead to parsing errors if the US decimal point format settings are changed on the user’s pc.
Fixed a bug in the TSVG2ImageList which led to small artefacts being visible in the rendered images of the image list. The problem was that the bitmaps where added premultiplied to the list, they should first be unpremultiplied.
Added parameter “PreserveContentBitmap” to the SVGRenderToBitmap function in unit BVE.SVG2Elements.VCL. If set to TRUE, the bitmap will not be cleared (with alpha black = $00000000), but the SVG graphic will be drawn on top of the existing bitmap content. This parameter is set to a default value of FALSE.
The TSVG2ImageList object will initialize a bitmap with the clear colour and then call this function with the parameter set to TRUE, so the clear colour is preserved.
Version 2.2 update 8, 6-12-2017
Fixed bug in sax parser, first node is not cleared from NodeStack, which resulted in big memory consumption on repeated parsing (random star example)
Fixed bug in triggering text event, bug in character cell bounds calculation
Fixed a bug, introduced in Update 7, if windows system DPI is changed, the SVG rendering scale was not correct.
On some Windows systems the Direct2D DC rendering does not work, resulting in black bitmaps. I replaced the DC rendering target with a WIC rendering target, which was already used but only for intermediate buffers.
Fixed a bug, if an Base64 encoded embedded SVG image contains Linefeed characters (#10), this would result in a image decoding error. This is solved by adding #10 to the entity list of the XML reader in BVE.SVG2XMLReader.pas
Added support for complex font-face-src CSS definitions and SVG elements. This now supports multiple sources and the “local” directive.
Removed some unused code in BVE.RenderContextDirect2D.VCL.pas

Version 2.2 update 3, 4-5-2017
Solved a bug parsing comments in CSS
Solved a bug parsing Unicode references in glyph definitions
Added CalcIntrinsicSize to TSVGRoot to calculate the initial size of an SVG in pixels, also if it it’s size is given in percentages or not defined at all. In controls this will now be called through the “CalcSize” procedure.
Fixed a bug in TSVG2Graphic Draw procedure placing the bitmap origin
Version 2.2 update 2, 9-4-2017

Biggest changes are:
- Added SVG filter effects functionality
- Added SVG events functionality

Added functionality to store multiple outer SVG docs in one TSVGRoot element that reference each other.
Added TSVGRenderContextManager for managing the selection of a render context type and the appropriate object types for buffers and pathdata
Created a new VCL Viewer demo application
Replaced some types with special types to have more control, TSVGFloat for double or single, TSVGPoint for TPointF, TSVGMatrix for TMatrix, TSVGRect for TRectF, default float is now a double
Split the style attribute list of the rendering elements into StyleAttributes, InlineStyle And StylesheetStyle, so the correct priority of styles can be implemented.
Simplified the code by placing shared objects in the SVGRoot, in stead of passing them as parameters in functions, for example CTM (current transformation matrix), CVP (current viewport), CSA (current style attribues), CRC (current render context)
Solved xml entity parsing bug
Solved a bug in parsing xml namespaces
Solved some viewport bugs
Solved bug in pattern rotation
Enabled parsing of embedded SVG files within image elements.

Split axis-aligned and non-axis-aligned clippath rendering on VCL. axis-aligned will be faster, non-axis-aligned slower but more accurate, using a alpha-mask
Created a seperate unit “BVE.RenderContextCanvas.FMX.pas” for the render context implementation for FMX.
