Adds a global API to notify devs / users of deprecated features.
- Custom callbacks may be added
- By default, remembers message text and only sends each message once
- Sends to console.warn by default
```ts
// Add a custom notification when a warning is encountered
const warnMessage = (message: string, source?: object) => {
addToast({ message, detail: object })
}
LiteGraph.onDeprecationWarning.push(warnMessage)
```
```ts
// Debugging flag. Repeats deprecation warnings every time they are reported.
// May impact performance.
LiteGraph.alwaysRepeatWarnings = true
```
Generate a warning
```ts
import { warnDeprecated } from "@/utils/feedback"
warnDeprecated(
"[DEPRECATED] graph.oldFeature() will be removed from Litegraph. " +
"Please use graph.newFeature() instead. https://helpful.site/faq",
objectThatCausedThis
)
```
