- set correct default for fill/stroke unset color
- fixes #398

- fixes #191

- added test image for new issue

Fix issue with percentage unit in "stroke-width", now taken from the viewbox width/height normalised diagonale for x/y elements e.g. circle
Test images and svg under #338

- fixes #58

Fix Issue #385, using TextBounds.Width rather than path bounds to ensure proper font alignment for "middle" and "end" - see also "text-align-03-b"

- added "stroke-dashoffset" support
- added "painting-stroke-04-t" to "PassingTests" (csv/txt)
- fixes #388 

- added a few of them to passing image comparson tests

- added image broken by regression to tests (__Flag_of_the_United_States)
- added some passing issue specific tests to image comparison tests

- first try for a matching comparison test
- compares down-scaled gray-scale images pixel-wise
- see #378

- ignore elements with recursive references
- fixes stack overflow for test image struct-use-12-f.svg

- ignore textLength attribute if X attribute is list
- add test images

- fixed a few other tests by using the Svg DTD Resolver to avoid web requests

- suppress warning CS1591: Missing XML comment for publicly visible type or member
  to avoid to overflow the build log with warnings
- fixed the rest of the documentation warnings in SVG project
- ignore all failing tests for the time being

- Fix: adjustment is wrong in lengthAdjust='spacingAndGlyphs'.
- Add test images.

Updated threading tests to use the resource file, updated the file loader in the test helper to be flagged as obsolete and changed the working of the multi-threading fail test since this is not always failing with the error while processing the SVG. If it's not failing now it will be flagged inconclusive.

- moved passing/failed/other tests into separate tabs
- removed functionless menu
- changed title

- show description for W3C tests

- fixes text-text-12-t.svg

- use GetInheritedAttribute() to correctly handle "Inherit" value
- fixes inheritance of these attributes from groups
- fixes alignment in types-basic-01-f.svg test

- ensures that #243 is fixed

- calculate svg element bounds considering child svg fragments
- consider svg fragment offset in bounds / dimensions
- do not create view box if none is defined
- fixes #244

- relative URL have not been loaded (example: masking-path-06-b.svg in test data)
- Updated passing tests (note: not all changes are related to the current fix)

- a view box does not need a clip region, this breaks the overflow
handling
- overflow handling:  handle overflow attribut "Inherit" as Visible and
"Scroll" as Hidden as per W3C documentation
- fixes #279

- accidentally committed version with incorrect expected values

SvgTextBase Text property setter resets Node collection to have single content node with provided text.

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.
