| 24 | * with Fence::waitForever without a corresponding signal to unblock |
| 25 | * This happens during attempts to cache SkImage instances across frames |
| 26 | * especially in circumstances using RenderEffect/SkImageFilter internally. |
| 27 | * So detect the corresponding GL Vendor and driver version to determine if |
| 28 | * caching SkImage instances across frames is supported. |
