Bug 308520 – [svg2] comprehensive test cases for parsing path data of the d attribute in path element

• Component: SVG
• Status: RESOLVED FIXED

[Karl Dubost]

The SVG2 Path Data for the d attribute of the path element is defined in 
9.3.2. Specifying path data: the ‘d’ property
https://w3c.github.io/svgwg/svg2-draft/paths.html#TheDProperty

the d attribute takes a string with a specific grammar defined in 

9.3.9. The grammar for path data
https://w3c.github.io/svgwg/svg2-draft/paths.html#PathDataBNF

and has error handling constraints:

9.5.4. Error handling in path data
https://w3c.github.io/svgwg/svg2-draft/paths.html#PathDataErrorHandling

The current tests in https://wpt.fyi/results/svg/path
has a partial coverage of the constraints. 

This is an attempt at making more modern tests than the current ones and add tests of cases not being tested currently.

^ Blink has these API test cases. Might be good to see if these can be converted into testharness based test cases.

I have already a series of test case. But it would be good to compare mine with the others.
