- Very initial support of CSS stylesheets in the SVG via including the
ExCss and Fizzler libraries
- Bug fixes with path rendering
- Improvements to the API for loading an SVG file

-Fixes issues with colors not parsing correctly. Saving an SvgDocument
resulted in RGB color values being converted to well known color names.

-Compile regex statements to improve performance.

-Make rendering a document threadsafe.

Add support for unknown svg element and non svg element: useful for not removing unknown xml tag from document when loading a file

Add support for unknown svg element and non svg element: useful for not removing unknown xml tag from document when loading a file

- exponent support in units (IE sucks!)
- inherit font-size and font-family from root element on text elements
- allow empty text elements if there is a non empty TSPan

- Changes to get texts displaying bold / normal weight
- Changes to get textspans work correctly
- Made (semi-hardcoded) document metadata section - allow reading and regurgitating metdata tag from an original source document
- Included image
- Modified paths to allow for scientific notation
- Included ability to have markers for path ends (arrow ends etc)

Removed some compiler warnings.

- Fixed a bug that caused <text/> elements to be parsed incorrectly, leading to exceptions within the document.

- Fixed #7986: public static SvgDocument Open(XmlDocument document) returns null: Implemented the proposed solution
- Added more XML API comments.
- Removed SvgVisualElementEvents.cs class - this was not used and not likely to be used

- Refactored SvgElementFactory to use the new SvgElementAttribute to get available elements.

- Fixed "#7522 support rotate(angle,cx,cy)". Added new properties and a new constructor overload to   SvgRotate in order to support the optional parameters.
- Removed redundant code from SvgElementFactory.

- Fixed #6324: SvgElement.PushTransforms and ViewBox - not necessarily related to ViewBox but every   element was 'resetting' the current graphics transform if the element contained it's own transform. This 
  was a very small fix for a large problem (SvgElement.PushTransforms Matrix transformMatrix = new   Matrix(); changed to Matrix transformMatrix = renderer.Transform; in order to inherit the current   transform.)
- Fixed #6344: Parsing document incorrectly parents elements when it encounters empty nodes which are   in a different namespace. Empty nodes are now ignored and current nodes are closed as required. We'll 
  see how this fix goes.
- Fixed #6381: Units in inches are incorrectly parsed as millimeters - problem was caused by some   copy/paste work.
- Graphics has been replaced by SvgRenderer. This is essentially a wrapper around graphics but will allow
  custom svg related properties in the future when needed.
- Removed ISvgRenderer: A concrete implementation is suitable.
- SvgElement.ElementName has been changed to non-virtual and is set by the parser instead of the   developer having to specify it when developing the class.
- Added more XML API documentation.

- Fixed support for text-anchor="middle" and text-anchor="end" for <text/> elements.
- Added more XML API documentation
- Added x attribute and y attribute support to <use/> elements.
