| * Verify if the provided vendor and version supports RenderEffect caching |

| * |
| * Certain Open GL Driver implementations run into blocking scenarios |
| * with Fence::waitForever without a corresponding signal to unblock |
| * This happens during attempts to cache SkImage instances across frames |
| * especially in circumstances using RenderEffect/SkImageFilter internally. |
| * So detect the corresponding GL Vendor and driver version to determine if |
| * caching SkImage instances across frames is supported. |
| * See b/197263715 & b/193145089 |
| * @param vendor Vendor of the GL driver |
| * @param version Version of the GL driver from the given vendor |
| * @return True if a RenderEffect result can be cached across frames, |
| * false otherwise |
