Previously, we repainted every frame on Windows at full refresh rate.
This is an enormous waste, as the UI will be static most of the time.
This was to work around a bug with `rfd` + `eframe`.
On other platforms, we only repainted every frame when a job was running,
which was better, but still not ideal. We also had a 100ms deadline, so
we'd repaint at ~10fps minimum to catch new events (file watcher, jobs).
This removes all repaint logic from the main loop and moves it into the
individual places where we change state from another thread.
For example, the file watcher thread will now immediately notify egui
to repaint, rather than relying on the 100ms deadline we had previously.
Jobs, when updating their status, also notify egui to repaint.
For `rfd` file dialogs, this migrates to using the async API built on top of
a polling thread + `pollster`. This interacts better with `eframe` on Windows.
Overall, this should reduce repaints and improve responsiveness to
file changes and background tasks.
Uses file modification timestamp polling for project config and objects to avoid unneeded complexity from the filesystem notification watcher.
Allows disabling `build_base` as well for projects using an external build system.
- Support `completed` field for objects in project config. In object tree, displays red for incomplete, green for complete.
- Add support for one-sided diffs. A project can include objects without an associated source file for viewing.
- Add versioning to AppConfig, supporting upgrades without losing user configuration.
- Allow config to specify object "target_path" and "base_path" explicitly, rather than relying on relative path from the "target_dir" and "base_dir". Useful for more complex directory layouts.
- Fix watch_patterns in project config not using default.
- Fix "Rebuild on changes" not defaulting to true.
- Keep watching project config updates even when "Rebuild on changes" is false.
- Disable some configuration options when loaded from project config file.
