/**
 * 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
