This is not the most efficient thing to do; a FIXME has been added
noting what is most correct.
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.
Removes 'FloatFlow' in favor of FloatBlockFlow, which is cointained
inside BlockFlow in a 'has-a' relationship. This avoids a bunch of
duplicated code.
This patch is for:
https://github.com/mozilla/servo/issues/1281
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.
