CMake: Always use a target for linking skia 2024-08-27 01:02:23 +00:00			`include_guard()`

CMake: Force-load fontconfig into dependencies of skia The dynamic shared lib build of skia doesn't seem to actually express any dependencies in its DT_NEEDED section, so we need to force-load fontconfig into the dependencies of the skia target to avoid runtime linker errors. 2024-11-07 19:44:40 +00:00			`include(fontconfig)`

LibWeb+LibGfx: Use Skia for text rasterization The main incentive is much better performance. We could have gone a bit further in optimizing the Skia painter to blit glyphs produced by LibGfx more efficiently from the glyph atlas, but eventually, we also want Skia to improve correctness. This change does not completely replace LibGfx in text handling. It's still used at all stages, including layout, up until display list replaying. 2024-07-25 18:59:30 +00:00			`find_package(unofficial-skia CONFIG)`
