* fonts: Add `FontIdentifier` and `LocalFontIdentifier` (#31658)Martin Robinson2024-03-141-3/+3
| | | | | | | | | | | | | | | | | | | Instead of using a simple `Atom` to identify a local font, use a data structure. This allows us to carry more information necessary to identify a local font (such as a path on MacOS). We need this for the new version of WebRender, as fonts on MacOS now require a path. This has a lot of benefits: 1. We can avoid loading fonts without paths on MacOS, which should avoid a lot of problems with flakiness and ensure we always load the same font for a given identifier. 2. This clarifies the difference between web fonts and local fonts, though there is more work to do here. 3. This avoid a *lot* of font shenanigans, such as trying to work backwards from the name of the font to the path of the font we actually matched. In general, we can remove a lot of code trying to accomplish these shenanigans. 4. Getting the font bytes always returns an `Arc` now avoiding an extra full font copy in the case of Canvas.

* layout: Turn on synthetic small-caps for layout 2020 (#31435)Martin Robinson2024-02-281-3/+6
| | | | | | | | | | | | Synthetic small caps is supported by the font subsystem, but this is disabled in Layout 2020. We can turn this on to bring support to parity with the old layout system. In addition to turning on synthetic small-caps this change also improves the way that they work. Before, synthetic small caps meant that every character was a small version of capitalized character. After this change, capital letters are larger than small caps versions of small letters -- matching other browsers and the common expectation of how small caps works.

* Don't panic when no font is found for a TextRun (#30581)Martin Robinson2023-10-191-6/+19
| | | | Instead of panicking when no found is found for a TextRun, instead print a warning. This prevents panics on pages with very large font sizes.

* Update dependencies to use new_debug_unrechableMatt Brubeck2018-06-061-2/+2

* Don't perform font matching for control charactersJon Leighton2018-05-191-52/+54
| | | | | | | | We can encounter control characters here, for example when processing a <pre> element which contains newlines. Control characters are inherently non-printing, therefore if we try to call find_by_codepoint for these characters we will end up triggering an unnecessary font fallback search.
* Add test for FontContext/FontGroup functionalityJon Leighton2018-02-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | Unfortunately, this required quite a bit of changes to the non-test code. That's because FontContext depends on a FontCacheThread, which in turn depends on a CoreResourceThread and therefore lots of other data structures. It seemed like it would be very difficult to instantiate a FontContext as it was, and even if we could it seems like overkill to have all these data structures present for a relatively focused test. Therefore, I created a FontSource trait which represents the interface which FontContext uses to talk to FontCacheThread. FontCacheThread then implements FontSource. Then, in the test, we can create a dummy implementation of FontSource rather than using FontCacheThread. This actually has the advantage that we can make our dummy implementation behave in certain specific way which are useful for testing, for example it can count the number of times find_font_template() is called, which helps us verify that caching/lazy-loading is working as intended.
* Lazy load fonts in a FontGroupJon Leighton2018-02-221-25/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a step towards fixing #17267. To fix that, we need to be able to try various different fallback fonts in turn, which would become unweildy with the prior eager-loading strategy. Prior to this change, FontGroup loaded up all Font instances, including the fallback font, before any of them were checked for the presence of the glyphs we're trying to render. So for the following CSS: font-family: Helvetica, Arial; The FontGroup would contain a Font instance for Helvetica, and a Font instance for Arial, and a Font instance for the fallback font. It may be that Helvetica contains glyphs for every character in the document, and therefore Arial and the fallback font are not needed at all. This change makes the strategy lazy, so that we'll only create a Font for Arial if we cannot find a glyph within Helvetica. I've also substantially refactored the existing code in the process and added some documentation along the way.

* Introduce CSSPixelLength and update NonNegativeLength.Boris Chiou2017-09-131-7/+8
| | | | | | | | | | | First, we define computed::CSSPixelLength which contains a CSSFloat, a pixel value, and then we replace computed::Length with CSSPixelLength. Therefore, the |ComputedValue| of NoCalcLength, AbsoluteLength, FontRelativeLength, ViewportPercentageLength, CharacterWidth, and PhysicalLength is CSSPixelLength. Besides, we drop NonNegativeAu, and replace computed::NonNegativeLength with NonNegative<computed::Length>. (i.e. NonNegative<CSSPixelLength>)
