Introduced RenderEffect API to handle consuming SkImageFilter parameters on RenderNode objects in order to support blur. Updated SilkFX demo to use RenderEffect APIs on RenderNode instead of BlurShader Bug: 168549524 Test: Added tests to RenderNode CTS test cases Change-Id: I5005a322a6d75438dd104e6915630264406cf771
