Britt Binler font: add bitmap font tests for BDF, PCF, and OTB formats 7mo ago

BSD-2-Clause.txt

font: add bitmap font tests for BDF, PCF, and OTB formats Add test coverage for bitmap font rendering using the Spleen 8x16 font in three formats: BDF (Bitmap Distribution Format), PCF (Portable Compiled Format), and OTB (OpenType Bitmap). Tests validate glyph rendering against expected pixel patterns. Addresses #8524.

CozetteVector.ttf

font: if VS15/16 not specified, prefer any presentation in explicit font Fixes #845 Quick background: Emoji codepoints are either default text or default graphical ("Emoji") presentation. An example of a default text emoji is ❤. You have to add VS16 to this emoji to get: ❤️. Some font are default graphical and require VS15 to force text. A font face can only advertise text vs emoji presentation for the entire font face. Some font faces (i.e. Cozette) include both text glyphs and emoji glyphs, but since they can only advertise as one, advertise as "text". As a result, if a user types an emoji such as 👽, it will fallback to another font to try to find a font that satisfies the "graphical" presentation requirement. But Cozette supports 👽, its just advertised as "text"! Normally, this behavior is what you want. However, if a user explicitly requests their font-family to be a font that contains a mix of test and emoji, they _probably_ want those emoji to be used regardless of default presentation. This is similar to a rich text editor (like TextEdit on Mac): if you explicitly select "Cozette" as your font, the alien emoji shows up using the text-based Cozette glyph. This commit changes our presentation handling behavior to do the following: * If no explicit variation selector (VS15/VS16) is specified, any matching codepoint in an explicitly loaded font (i.e. via `font-family`) will be used. * If an explicit variation selector is specified or our explicitly loaded fonts don't contain the codepoint, fallback fonts will be searched but require an exact match on presentation. * If no fallback is found with an exact match, any font with any presentation can match the codepoint. This commit should generally not change the behavior of Emoji or VS15/16 handling for almost all users. The only users impacted by this commit are specifically users who are using fonts with a mix of emoji and text.

font/coretext: shaping ligatures adds padding cells for replaced cells Fixes #1708 Harfbuzz does this automatically. Our tests for harfbuzz test this. We had a todo in CoreText to mimic this but wasn't sure if it was useful. Turns out, it is important (see bug!)

font: add stylistic variants for built-in font, fix naming convention Fixes #2364 This adds the bold, italic, and bold italic variants of JB Mono so it is built-in. This also fixes up the naming convention for the embedded font files across tests and removes redundant embedded font files.

JetBrainsMonoNoNF-Regular.ttf

font/coretext: shaper may return multiple runs and that's okay Fixes #1664 I previously asserted that we got exactly one run from CoreText because I assumed that our run iterator was perfectly splitting runs for CoreText. This assumption appears to be false and that seems okay. The test case in this commit produces two runs that are directly next to each other and there's no downside to simply iterating over them. So this commit changes to iterate over the runs.

font: treated fonts with mixed color/non-color glyphs as text Related to #1768 but doesn't fix it properly. This is a temporary hack to avoid some issues with fonts that have mixed color/non-color glyphs. If there are mixed presentations and the font does not have emoji codepoints, then we assume it is text. This fixes the typical scenarios. This is not a long term solution. A proper long term solution is to detect this scenario and on a per-glyph basis handle colorization (or the lack thereof) correctly. It looks like to do this we'll have to parse some font tables which is considerably more work so I wanted to do this first.

MonaspaceNeon-Regular.otf

font: insert blank cells for multi-cell ligatures for styling Up to this point, every font I've experienced with ligatures has replaced the codepoints that were replaced for combining with a space. For example, if a font has a ligature for "!=" to turn it into a glyph, it'd shape to `[not equal glyph, space]`, so it'd still take up two cells, allowing us to style both. Monaspace, however, does not do this. It turns "!=" into `[not equal glyph]` so styles like backgrounds, underlines, etc. were not extending. This commit detects multi-cell glyphs and inserts synthetic blank cells so that styling returns. I decided to do this via synthetic blank cells instead of introducing a `cell_width` to the shaper result because this simplifies the renderers to assume each shaper cell is one cell. We can change this later if we need to. Annoyingly, this does make the shaper slightly slower for EVERYONE to accomodate one known font that behaves this way. I haven't benchmarked it but my belief is that the performance impact will be negligible because to figure out cell width we're only accessing subsequent cells so they're likely to be in the CPU cache and also 99% of cells are going to be width 1.
