SSIA. Patch is coming.
Created attachment 215158 [details]
Coordinated Graphics already has its own implementation for encoding/decoding FilterOperations in Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsArgumentCoders.cpp and it works with FilterOperation::VALIDATED_CUSTOM typed filter operations too. r157803 caused build failure on USE(COORDINATED_GRAPHICS) platforms if ENABLE(CSS_FILTERS) is true due to duplicated encoder/decoder implementation.
An ideal fix would be to merge the two code paths ... but I don't know if
Apple wants FilterOperation::VALIDATED_CUSTOM or Coordinated Graphics platforms
could live without it. So the proposed fix is the most conservative way for
the fix without any behavioural change on any platform.
