We achieve this by adding a new Layout::ImageProvider class and having
both HTMLImageElement and HTMLObjectElement inherit from it.
The HTML spec is vague on how object image loading should work, which
is why this first pass is focusing on image elements.
This patch adds HTML::ImageRequest and HTML::DecodedImageData.
The latter had to use a different name than "ImageData", as there is
already an IDL-exposed ImageData class in HTML.
This makes hovering around on GitHub fast again, as it no longer
believes that the grid-template-areas property keeps changing
when it didn't :^)
Also made to_string() work for calc() values as well, since I stumbled
upon that while debugging this.
The completion callback currently only accepts a JavaScriptModuleScript.
The same callback will need to be used for ClassicScript scripts as well
so allow the callback to accept any Script type. The single existing
outside caller already stores the result as a Script.
If just .to_px() is used the height can end up as the float `inf` or
`nan`. This caused an OOM when loading Polygon as this `inf` would
become a `nan` and propagate to the SVG painting, which then attempts
to draw a path with nan control points, which would make the
Gfx::Painter infinitely split the path till it OOM'd.
Previously, the width and height of grid items were set to match the
size of the grid area they belonged to. With this change, if a grid
item has preferred width or height specified to not "auto" value it
will be resolved using grid area as containing block and used instead.
Using LengthPercentage instead of Length and Percentage separately
is going to allow GridSize to store calc() values. It also allows
to simplify some parts of layout code.
While it's possible to getComputedStyle() on an unconnected element,
the resulting object is not supposed to have any values, since we can't
resolve style without a document root anyway.

If there are min or max size constraints in the cross axis for a flex
item that has a desired aspect ratio, we may need to adjust the main
size *after* applying the cross size constraints.
All the steps to achieving this aren't mentioned in the spec, but it
seems that all other browsers behave this way, so we should too.
size_t should be used instead of int in loop counter and to store
rows/columns positions because they can't be negative values.
This allows to remove some static casts to int.
Instead of bailing after resolving one violated constraint, we have to
continue down the list of remaining constraints.
We now also call the constraint solver for all replaced elements with
"auto" for both width and height.

This lets elements figure out if they're visible within the viewport or
not, so they take appropriate action.
Fixes the issues with animations not starting until the viewport was
resized or scrolled.
1. Stop using -1 to indicate infinity value of growth limit. Just use
INFINITY for that.
2. More complete implementation of "Expand Flexible Tracks" step.
3. Return AvailableSize from get_free_space: spec says that this
function can return indefinite size and it is ok.
Due to 582c55a, both `must_set()` and `set()` should be providing the
same behavior. Not only is that a reason to remove `must_set()`, but
it also performs erroneous behavior since it inserts an element at
a specified index instead of modifying an element at that index.
If the parent BFC can come up with a nice stretch-fit width for the flex
container, it will have already done so *before* even entering flex
layout. There's no need to do it again, midway through the flex layout
algorithm.
This wasn't just unnecessary, but we were also doing it incorrectly and
not taking margins into account when calculating the amount of available
space for stretch-fit. This led to oversized flex containers in the
presence of negative margins.
Fixes#18614
`calculate_max_content_height` expects the available width as the
second argument. However, the available height was mistakenly passed
before. This did not seem to cause any problems because TFC currently
does not respect height sizing constraints but still needs to be fixed.
The root element font metrics were getting queried again and again
during style computation. Before this change we would do some work to
recalculate them each time.
This patch simply caches them in a StyleComputer member. Since style
updates always start with the root element, we know that it'll be
up-to-date by the time we look at any other element.
Before this change, we were spending ~5% of CPU time on Google Groups
in root_element_font_metrics().
This is an oversized hammer for sure, but we have to make sure the
layout tree gets rebuilt in case the object representation changes.
Since "throw out the entire layout tree" is the finest tool we have
right now, it'll have to do.
This fixes an issue where the eyes on Acid2 would sometimes not show up
until the next layout invalidation occurred.
