+/**
+ * Verify if the provided vendor and version supports RenderEffect caching
+ * behavior.
+ *
+ * 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
