Fix #324, thanks to Lucien!
This PR doesn't provide a perfect support of flexbox, but it shouldn't introduce any regressions and doesn't crash with any of the W3C suite tests. And it's not that bad with real-life cases
What's not supported yet:
Many TODOs are in
I'll fix some easy-to-fix problems before merging this PR, using the W3C tests and some real case uses. I'll need to add tests in WP too.
block_level_layout is not needed as width and height have already been fixed during flex layout.
Time to merge. We have almost 50% of the W3C test suite passing, with a lot of tests relying on Regions or Grid, and some old tests based on old properties that have been removed. There's no crash with the test suite and hopefully no regressions.
Page breaks and floats for example could be highly improved, but fixes can be added on
