Fix:
Now the application make sure to set back the old culture even an error
occurred.
SvgColourConverter.ConvertFrom
SvgPathBuilder.ConvertTo
SvgDocument.Write
SvgExtentions.GetXML

Add:
Attribute: "shape-rendering"

Change:
- Many other properties were unknowingly overloaded. I changed them to
override.
- Some methods or structures need the [CLSCompliant(false)] Attribute.
For example the Enums.TryParse extension. This extension has the where
condition IConvertible. IConvertible is [CLSCompliant(false)] and that
the reason why it is correct to mark the Enums.TryParse extension also
as [CLSCompliant(false)].
- Property "float Opacity" in SvgElement was unknowingly overloaded in
SvgGradientStop as string [stop-opacity]. In the end this property was
only used as float. I changed the SvgGradientStop.Opacity property from
string to float and to override.

Extended the Marker start/mid/end getters with a function to return null if the property was set to none. This will prevent nullpointer issues when having none as one of the items.

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

- Fixing #8494: Polyline fill being ignored. This appears to have been done on purpose (the Fill property was overridden to return null) but without reason. GIMP, Firefox 3 & Opera 9 all render the fill.

- Fixed [workitem:7526] whitespaces \t \r \n in path and points result in exception. The   SvgUnitCollectionConverter (SvgUnitCollection.cs) class had to split on \r, \t and \n aswell as ' ' and ','.
