Typo
Make the test suite 5x faster.

When comparing image pixels:

* Inline the get_pixel lambda
* Move it out of the loop
* Compare big chuncks (whole image, row, RGBA pixel) to avoid entering
inner loops if they are equal.

Needs review for correctness.
Take image from output because of minor variations in svg/png (ex: different shade of the same color)
Add some attributes to be none-inherit for correcting errors
Mainly Adapt the code to work with the new definition of 'filter_fill_or_stroke' (now 'paint')
Re-write almost the all 'drawn_pattern' function to be more specific, to work better actually, same for 'use' function about url
Re-write old 'filter_fill_or_stroke' function into a new 'paint' function which work better
Failed test which work now
Old failed tests which work now so they have been moved with other succeed tests
