`background-size` per CSS-BACKGROUNDS § 3.9.
Nearest neighbor interpolation is used for `crisp-edges`, like Firefox.
A note has been added that we could do better if we wanted to.
Multiple backgrounds are not yet supported.
Rebase of #4368. Fixes#4368.
Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.
Moved from #4544, because Critic.
Fixes#4544.

It wasn’t wrong, but it could be a lot shorter.
* Use try! and match_ignore_ascii_case! macros whenever possible
* Use expect_comma() instead of parse_comma_separated() when comma-separated values don’t have the same syntax
* Prefer Parser::expect_* methods over doing the same with Parser::next
* Take advantage of parse_nested_block returnin the return value of the closure
* Use try! more.

Move culling of transparent display items to paint task rather than display list builder, so that hit testing detects mouse over on transparent background elements.
Sometimes, the root pipeline title is sent before the compositor has created the root pipeline, so also request the main page title once the initial frame tree has been sent.
Also introduce a clear() function to layout data which will be used to clear items such as compositor layouts.
Clear the layout data when a node becomes display:none.

When an iframe is created with display:none it sets the root layer to be zero width and height. When updating the rect of the iframe from layout send the entire rect rather than just the new origin, which handles the case where the iframe has been made visible and now has a non-zero rect.
