           Summary: Implement RemoteFontStream's skip behavior (in
                    FontCustomPlatformData.cpp)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Other
            Status: UNCONFIRMED

          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org

The implementation of RemoteFontStream (in WebCore/platform/graphics/skia/FontCustomPlatformData.cpp) is not complete, missing 'skip' feature. Though Chromium port doesn't use the skip feature (it reads the whole stream data at once), other ports using Skia might encounter problems if the stream is passed to Skia. The SkStream::skip() and SkStream::read(NULL, skip) functionalities are used frequently in Skia code. This will cause failures when loading a font from a stream.
