|  | * 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. |

|  | * @param version Version of the GL driver from the given vendor | 
|  | * @return True if a RenderEffect result can be cached across frames, |
