Depends on https://github.com/zed-industries/font-kit/pull/2 and https://github.com/kvark/blade/pull/77 This change enables Blade to be also used on MacOS. It will also make it easier to use it on Windows. What works: most of the things. Zed loads as fast and appears equally responsive to the current renderer. <img width="306" alt="Screenshot 2024-02-11 at 12 09 15 AM" src="https://github.com/zed-industries/zed/assets/107301/66d82f45-5ea2-4e2b-86c6-5b3ed333c827"> Things missing: - [x] video streaming. ~~Requires a bit of plumbing on both Blade and Zed sides, but all fairly straightforward.~~ - verified with a local setup - [x] resize. ~~Not sure where exactly to hook up the reaction on the window size change. Once we know where, the fix is one line.~~ - [ ] fine-tune CA Layer - this isn't a blocker for merging the PR, but it would be a blocker if we wanted to switch to the new path by default - [ ] rebase on latest, get the dependency merged (need review/merge of https://github.com/zed-industries/font-kit/pull/2!) Update: I implemented resize support as well as "surface" rendering on the Blade path (which will be useful on Linux/Windows later on). I haven't tested the latter though - not sure how to get something streaming. Would appreciate some help! I don't think this should be a blocker to this PR, anyway. The only little piece that's missing for the Blade on MacOS path to be full-featured is fine-tuning the CALayer configuration. Zed does a lot of careful logic in configuring the layer, such as switching the "present with transaction" on/off intermittently, which Blade path doesn't have yet.
