Fix scaling of Draw(width, height)

Test runner: minor GUI improvements

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

Added test description in test runner

- show description for W3C tests

Add a text copy of the Ms-PL and update Markdown formatting

Fixed inheritance of  text-anchor and baseline-shift attributes

- 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

Found better solution to SvgClosePathSegment tested with Tiger.

Reverted unneeded part of previous fix

- caused regression

Prevent crashes on zero length segments or paths

Correctly handle embedded SVG fragments without viewbox

- fixes __tiger.svg test image

- 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

Use Hidden as default SvgOverflow value

- changes behavior to be as described in this file and in the W3C test
masking-path-03-b
- fixes that test
- this has been a regression after removing the unconditional clip box
for every view box, (see #279)

Fixed PushTransform for SvgUse

Do not create a clip region for view box

Allow relative paths for image URLs

- fixed matrix order (Prepend instead of Append)
- fixes #64 (see __issue-064-01.svg and __issue-064-02.svg)
- fixes test for struct-use-03-t.svg

- 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

Added array caching to AddToPath for a significant performance increase.

Fixed BoundsTest

- accidentally committed version with incorrect expected values

Add transform to bounds calculation in path based objects

see #281
