Perfetto has significantly less overhead. The User facing API is
mostly unchanged:
Here are the differences:
- SYSTRACE_ENABLE() does nothing on ANDROID, initializes systraces on darwin.
- SYSTRACE_DISABLE() is removed.
- A new "gltfio" tag is added.
- SYSTRACE_TAG *must* be defined before including `utils/Systrace.h`
- `utils/Systrace.h` should not be used from a public header
- the new SYSTRACE_TAG_DISABLE disables systrace at compile time
For android a data source MUST be created in the perfetto config:
```
data_sources {
config {
name: "track_event"
track_event_config {
enabled_categories: ["filament", "jobsystem", "gltfio"]
disabled_categories: "*"
}
}
}
```
This can for example be added to AGI's custom/advanced config.
