`cellspacing` attribute per HTML5 § 14.3.9.
Table layout code has been refactored to push the spacing down to
rowgroups and rows; this will aid the implementation of
`border-collapse` as well.
This commit also fixes two nasty issues in table layout:
* In fixed layout, extra space would not be divided among columns that
had auto width but had nonzero minimum width.
* In automatic layout, extra space would be distributed to constrained
columns as well even if unconstrained columns with percentage equal to
zero were present.
§ 12.3-12.5.
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.
...and vice-versa. This is not a complete fix for all mixed-direction layout
cases, but it fixes enough problems to make some simple test cases pass, like
tha attached reftest.
There are FIXME comments for many of the remaining issues. In particular,
this does not yet handle RTL layout of fixed/absolute elements.
A race condition exists where pipelines that are removed from a document
may not ever trigger a paint for that pipeline. The compositor relies
on a paint occurring for each pipeline before outputting the image when
in reftest mode.
`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.

Moved from #4544, because Critic.
Fixes#4544.

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.

Inline fragments that are part of a text run don't have interior borders.
So don't draw interior borders or include them when calculating positioning.
Fixes https://github.com/servo/servo/issues/4658, where multiple text nodes that are adjacent have distinct borders.
r? @Ms2ger, @pcwalton
Instead of looking at the boundaries of the text run, set the border
width to zero and the border style to none on border sides that are not
the outermost for a node container that is display: inline.
The borders_a.html ref test had a WA to avoid displaying a spurious
black pixel at (0,0). Details are at
https://github.com/servo/servo/issues/2879
The WA can be removed since the bug is no longer reproducible.
Prior to incremental layout, the code would remove the existing
construction result. However, with incremental layout the construction result
is cloned rather than removed. This change ensures that the previous
construction result is cleared when an element's display type
changes to none.
CSS-TEXT-3 § 7.3.
`text-justify: distribute` is not supported.
The behavior of `text-justify: none` does not seem to match what Firefox
and Chrome do, but it seems to match the spec.
Closes#213.
This patch also makes Servo not crash when
`generated_containing_block_rect()` is called on a list item (as, for
example, GitHub does), and for good measure I added the fix to other
flows as well.
'oblique' font-style is not supported now.
When I checked freetype.h, same macro is used for italic and oblique.
/* FT_STYLE_FLAG_ITALIC :: */
/* Indicates that a given face style is italic or oblique. */
So, when font style is 'oblique', enable flag for italic.
With tests/html/test_italic_bold.html, it works well.
Conforming to section 5.5 (Rounded Corners/Overlapping Curves) of "CSS
Background and Borders Module Level 3", border radii on elements whose
border curves would have overlapped are uniformly scaled down to the
point that they no longer do.
