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"

changed rounding behavior of float to int color conversion from floor() to round()

Issue 225 - Image with large embedded image fails to render

reference: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/pattern

This is huge especially for the low values because human eyes distinguish darker colors much better.

- Changed SvgImage.Href property from Uri type to String to avoid UriFormatException if Uri contains too much data
- Changed GetImage to receive a string instead of Uri object.
  - Created a temp Uri object in method with substring of allowed length and using this to determine Uri characteristics

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.

This reverts commit a7097113.

This reverts commit 480a54d8.

Based on Issue #204.
Now users can add customer fonts/ private fonts to
SvgElement.PrivateFonts.

Unit Test:
Add Test: PrivateFontsTest
Add Resources from PrivateFontsTest.
Add SvgTestHelper
Change MultiThreadingTest, now based on SvgTestHelper to use shared code
(no code duplication)

Note:
MuliThreadingTest TestFile is not available. The vvvv/master should add
the test file to the resources or other developer can not test the svg
engine.

Load an attribute only once if possible.

Pull Request from master

Add: SvgShapeRendering, SvgTextRendering and SvgImageRendering in
SvgAttributeCollection.IsInheritValue

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.
