Use explicit height of inline-block fragments
When an explicit height is used for inline-block fragments, the line spacing algorithm should use that for the height above the baseline, instead of the intrinsic one.

stylo: Improve restyling performance
This commit adds hooks to the Servo style traversal to avoid traversing all the
DOM for every restyle. Additionally it changes the behavior of the dirty flag to
be propagated top down, to prevent extra overhead when an element is dirtied.
This commit doesn't aim to change the behavior on Servo just yet, since Servo does extra job when dirtying the node related with DOM revision counters that might be necessary.
CC @asajeffrey for the DOM revision counters stuff. When a node is dirty, do all its descendants really need to increment the revision counter, or is this an unintended effect? My intuition is that this is hurting performance quite a lot for servo.

Fix table vertical alignment (middle, bottom)
<!-- Please describe your changes on the following line: -->
Fixes table cell vertical alignment (middle, bottom, not yet baseline) when the row contains cells of differing heights.
Moved the work done earlier by @notriddle into a separate public function on TableCellFlow. This function is then called by TableRowFlow once the cell's block size has been calculator.

The 'box_sizing_boundary()' method return the border_padding width in
certain direction if fragment has property 'box-sizing: border-box'. The
'border_padding' field should be initialized before.
Iterate over the items, create lines from them, resolve flex lengths
against them, set their inline size and margin lengths, and align them
according to 'justify-content', 'align-content' and 'align-self'.
As the flexbox spec change in May 2016, the absolutely positioned
children painting order no longer follow the `order` property, thus we
can simply filter them out.
Also sort items by the order field of 'FlexItem', no longer do two
vtable lookups in each compare.
These 'is_wrappable' flag can be used to determine if a flex flow can be
multi-line. The 'is_reverse' flag is replaced by 'main_reverse' and
'cross_reverse' since flex flow can go reverse individually in main and
cross direction.
Extend fields of `FlexItem` struct with values that are necessary to
resolve flexible lengths, and the 'order' property. Add other methods
for size computing to make the code more modular.
layout: Clear non-inherited properties on anonymous block
<!-- Please describe your changes on the following line: -->
This is one of my pull requests that imlement basic flexible box layout.
This pull request adds a `modify_style_for_anonymous_flow()` function to use initial values for non-inherited properties and parent values for inherited properties as the flow style. It also set border and outline to zero and set the display property from the parameter. This function may also be reused to modify style of anonymous table object in the future.
Part of code comes from `cascade_anonymous()` from @SimonSapin .

Add a modify_style_for_anonymous_flow() function to use initial values
for non-inherited properties and parent values for inherited properties
as the block style. It also set border and outline to zero and set the
display property from the parameter.
Treat flex flow as block in float calculation
<!-- Please describe your changes on the following line: -->
This is on of my pull requests that implement basic flexible box layout.
Currently call `is_block_like()` on flex flow returns false. This would fix some errors in tests, for example 'flexbox-justify-content-horiz-001b.htm'.

This was making us fall in a loop where the start split was empty, but we didn't
ignore it because the current fragment had this flag, but then we treated it
differently depending on the white_space property.
Not totally sure this is the proper fix, but it makes sense to me. In case it
is:
Fixes#12369.

As a follow-up, we could move all the data living under a mutex in the
SharedLayoutContext only in order to create the local context to the same place.
This should increase animation performance when there are multiple animations in
one page that happen to be on different threads.

Text fragment color merge
The display list item for a line of text has a single color assigned for
it, so text fragments with different colors cannot be merged.
There is no issue number for this, as far as I know. I found this while
trying an internal program that uses red asterisks for required text
fields.
