## API
| Function            | Description                                                       |
| ------------------- | ----------------------------------------------------------------- |
| `makeX(...)`        | Creates an RHI resource and returns its handle                    |
| `deleteX(handle)`   | Releases the resource and invalidates the handle                  |
| `releaseX(handle)`  | Releases the resource but keeps the handle valid                  |
| `getXInfo(handle)`  | Returns backend-independent information about the resource        |
| `getRawX(handle)`   | Returns backend-specific raw GPU handle                           |
| `getRawFrame()`     | Returns backend-specific raw GPU frame resources                  |
