WR now has a concept of font templates and font instances. This makes the WR font interfaces closer to Cairo and Gecko, and also makes some future performance optimizations possible. A font template is the font family, and data backing the font. A font instance is a reference to a font template and per-instance options, such as font size, anti-aliasing settings etc. To update Servo in a minimally invasive way, I added a new font cache call, that creates a font instance. This means that when a font is created, and doesn't exist in the cache there are now two calls to the font cache thread. We could refactor the font cache to make this work in one call, which we should do in the future. However, refactoring the font cache is a large chunk of work by itself. The extra call is only when a font doesn't already exist in the font context cache, so it should have minimal performance impact. |
