This is a non-standard API that other browsers implement, which
highlights matching text in the current window.
This is just a thin wrapper around our find in page functionality, the
main motivation for adding this API is that it allows us to write tests
for our find in page implementation.
If a flex item has a preferred aspect ratio and the flex basis is not
definite, we were falling back to using stretch-fit for the main size,
since that appeared to match other browsers.
However, we missed the case where we actually have a definite cross size
through which the preferred aspect ratio can be naturally resolved.
To get away from the ancient (and buggy) text layout code in
Gfx::Painter, we want to remove all the uses of Painter::draw_text().
As a first step towards this, we implement the draw_text() display list
command in terms of the draw_text_run() command by performing the very
simple necessary layout in draw_text() beforehand.
The values aren't that complex, so it doesn't make much sense to have a
dedicated generator for them. Parsing them manually also allows us to
have much more control over the produced values, so as a result of this
change, EasingStyleValue becomes much more ergonomic.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
The DocumentTimeline constructor used the current millisecond time to
initialize its currentTime, but that means that a newly created timeline
would always have a different time value than other timelines that have
been through the update_animations_and_send_events function.
