Adding automatic pass/fail detection to test suite Warning! This is super slow to run and might even crash your browser. Disabled some failing tests while perfecting the comparison algorithm. A canvas render is compared with the expected result based on the SVG test suite. There are always some minor difference. If a pixel is slightly off target, this is treated as more correct. SVG renders are re-parsed using the parser and rendered to Canvas, then compared. Bugs in the parser and canvas rendering can worsen the score of this mode. There is currently no way to automatically test the VML output.
