Copy the nodes of a SvgElement when creating a deep copy.

Nested svg areas are misplaced or invisible 

SvgPointCollection ToString method fix

Fix fill-opacity/stroke-opacity wrongly inheriting from opacity when …

Fix stack overflow exception for em font-size value type

Added a test with a SvgText element where the whole text element was not written to XML of a deep copy of the SvgDocument.

If the root svg uses transformations ( e.g. defines a viewBox and
different width and height) the nested svg areas are misplaced or
invisible.

SvgPointCollection.ToString method modified to return valid coordinate string with each coordinate pair separated by whitespace and their x and y values separated by comma.

made SvgImage.GetImage public

fixed SvgImage.GetImage

[bugfix] now pattern reads proper transform named "patternTransform"

Update to fix Draw(Height,Width) overload

As long as the functions AdjustForViewBoxWidth and
AdjustForViewBoxHeight are not fully developed pay attention that the
ViewBox width and height will not mismatch the positions of the marker
element then one of them are zero.

This changes are based on Issue #212 from mater.

Add: Quick solution to avoid  ViewBox width or height zero calculation.
Add: UnitTests

Create metafile rendering Unit Test based on Issue #210 from master.

A NullReferenceException occurred when the SVG XML will be loaded over
the textbox. The reason is that in this case the svgDoc.BaseUri is null.
