This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
The main thing that is missing is validating certain pieces of data
against XML productions in well-formed mode, but nothing uses
well-formed mode right now.

This a simple RAII helper for the BorderRadiusCornerClipper it
samples under the corners on construction, then blits them back
on exiting the scope. This encapsulates a fairly common pattern.
Note: With this change the border-radius is clipped if ethier the
overflow-x or overflow-y is hidden (it is a little unclear what
happens if just one is set, but it seems like most browsers
treat one set + border-radius the same as if overflow: hidden
was set).
Previously, set_needs_display() was passed an empty rectangle in
ImageStyleValue::resource_did_load(). This led to the browser not
doing a repaint when the image loaded.
Fixes#14435
When swapping both values to perform the actual calculation, we need to
consider that `A + B == B + A`, but `A - B != B - A`, so turn it into
`-B + A`.

This commit adds some finagling and shrinking of the corner bitmap
to handle drawing shadows on elements where the shadow radius >
half the width or height of the element. Previously things would
go horribly wrong when this happend.
There could still be some edge cases, but things seem to be working
fairly well now.
This fixes a issue due to the background/border painting using
.to_rounded<int>() to get an IntRect, but shadow painting was using
enclosing_int_rect().
enclosing_int_rect() uses some floors/ceils and does not always match
.to_rounded<int>().
This now allows passing a 'fill_color' to the blur, any fully
transparent pixels will be replaced with this color (with the alpha
set to 0).
For box-shadows, if this color is set to the same as the shadow,
the issues around the fringes are fixed. This also fixes some places
where dark shadows appeared light / the wrong color.
With this change the blur no longer dominates the profile. On my PC
it is down to 27% (which is the same as the AA ellipse painting).
The box-shadow.html test page now also feels more responsive.
Previously we forwarded all event handler attributes to Window from
these two elements, however, we are only supposed to forward blur,
error, focus, load, resize and scroll.
This allows HTMLCanvasElement and WebGL rendering contexts to share
their lifetime, as JS allows them to arbitrarily access them at any
time and WebGLRCB.canvas expects a non-null return value.
This allows HTMLCanvasElement and CRC2D to share their lifetime, as JS
allows them to arbitrarily access them at any time and CRC2D.canvas
expects a non-null return value.
To achieve this goal:
- The Browser unveils "/tmp/portal/filesystemaccess"
- Pass the page through LoadRequest => ResourceLoader
- ResourceLoader requests a file to the FileSystemAccessServer via IPC
- OutOfProcessWebView handles it and sends a file descriptor back to
the Page.
The lack of the commit() before returning the x_value here meant,
that in parse_background_value() the token stream would be one token
behind after parsing the background-size. This led to it to returning
null, after it sees the unexpected 'second' contain / cover token.
With this change all of backgrounds.html is working again.
This prevents font-face rules without a block statement from crashing
LibWeb during CSS parsing.
The issue was discovered by Lubrsi during CSS parser fuzzing. :)
Fixes#14141.
This commit adds support for using all your favorite border radii with
box-shadow, that is elliptical, circular, rounded rectangle etc. :^)
There is some work needed to make this more performant. The larger
your border radius is the larger the corner bitmap needs to be,
which means more time spent in FastBoxBlurFilter. There are probably
some tricks to bring this down.
Fixes#14325
We were not applying the distributed space to the used offset of flex
items, as we were only assigning the margins to the layout state of the
box, not the internal FlexItem::margins.
