Added a flags variable inside Node to represent boolean flags, with
is_in_doc being the first of them. It is updated whenever a node is
appended or removed from a parent.
This patch is for:

This will allow us to stop going to the DOM in order to handle iframe
sizing. Instead we can just store the pipeline and frame IDs of iframes
inside the flow tree itself.
Instead we do selector matching again, then diff the style structs to set the
"restyle damage" bits which are used to prune reflow traversals.
Also don't force a reflow when timers finish, because individual DOM methods
should already take care of that.
This reverts commit e8ffac13d7, reversing
changes made to db923feffe.
Reverting this change because FreeType is *not* thread safe. See the
documentation here:
http://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html
"In multi-threaded applications, make sure that the same FT_Library
object or any of its children doesn't get accessed in parallel."
We will need to use a `MutexArc` instead.
I wasn't sure how to store @window in Location, so I just made it use @Page for now. I was going to implement stringifier, but sadly some of the webidl stuff is like 1 year out of sync.
This replaces flow construction with a strict bottom-up tree traversal,
allowing for parallelism. Each step of the traversal creates a flow or
a `ConstructionItem`, similar to how Gecko works. {ib} splits are
handled by not creating `InlineFlow`s until the containing block is
reached.
This should be able to be incrementalized by storing the `Flow` from
layout to layout, and performing fixups during flow construction
and/or wiping containing blocks in a previous pass.
I was going to add the Constructor overload, but that requires implementing that fallthrough case in CGCase, which I didn't feel like doing. At least we can compile the dict now.
Breaks the dependency between `gfx` and `script`, which is nice.
This exposed some performance issues with Rust's `Any` type, which I've filed:
