Add support for unknown svg element and non svg element: useful for not ...
Colors Fix, Perf Improvement, Thread Safety

-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.

Revert ".Net 3.5 Support and Rendering Improvements (Markers, TSpans, Paths, etc.)"
Support for 'slice' and fixed '...Max' in aspect ratio
Gradient Improvements

- Added support for the "gradientTransform" attribute on both linear and
  radial gradients. The matrix in this attribute needs to be applied to
  attributes with coordinate values on the gradient element in order to
  transform them into the correct coordinate space.

- Added support for a value of "pad" for the "spreadMode" attribute on
  both linear and radial gradients. This is the default value but was not
  implemented correctly. In order to implement, we examine the properties
  of the gradient along with the element to which the gradient is being
  applied to determine if we need to expand the bounds of the gradient to
  fill the element. If so, we do so and adjust the color stops and
  positions so they are correct for the new gradient bounds.

- Divided ISvgStylable into ISvgBoundable and ISvgStylable. The
  SvgUnit.ToDeviceValue method just needs bounds so it can take
  ISvgBoundable. Moved SvgDocument.GetDimensions() to SvgFragment and made
  SvgFragment ISvgBoundable.

- Fixed a bug in SvgFragment.PushTransforms where it was calling the
  SvgUnit.ToDeviceValue overload that takes no parameters. This overload
  doesn't work if the value being converted is a percentage. (The overload
  should probably be removed entirely, but we didn't take that on in this
  commit.)

- Fixed an issue in SvgGroup.Bounds where a child with empty bounds would
  cause the group's bounds to be reported as empty.

- Fixed broken build by adding missing SvgMarker.MarkerUnits property.

- Converted files that we touched with mixed tabs and spaces to spaces.
  Also removed unused usings from files we touched.

- Converted SvgLinearGradientServer to use properties without backing
  fields for X1, Y1, etc. in order to match SvgRadialGradientServer.

- Moved default value assignments into constructors for consistency.

Various Parsing Bug Fixes

- Implemented .Net 3.5 support mostly by removing ISvgEventCaller
functionality in .Net 3.5 build
- Added ability to parse colors such as rgb(#%, #%, #%)
- Fix issues with calculating the next coordinate after a close figure
and a relative move
- Allow the std. deviation in a gaussian blur to be a float.
- Allow "none" for a unit collection
- Allow gradients to reference other gradients defined later in the SVG
- Fix href attribute bug on the SVG use element
- Adding a descendants convenience methods (similar to the Xml to Linq
API)
- Removed non-functional property from the SvgDescription class to
encourage use of the Content property instead
Fix for GDI crash if stroke-dasharray contains value<=0

GDI Pen was crashing with some bad (Adobe Illustrator) data that had: stroke-dasharray="10,10,0"
Iteration 1 of tspan functionality
Iteration 2 of tspan functionality

- Support more font styles
- Fix problems with parsing 'em' svg units introduced by trying to parse
2e-5 double formats
- Move font properties to SvgVisualElement class as grouping elements
can also contain them
- Properly inherit font properties via the parent list
- Properly handle tspan offsets
- Support for .Net 3.5
