The various graphical filter elements are not properly built by WebCore.vcproj when ENABLE_FILTERS is defined. The main issues are that some key files are not included in the build, and some include paths are not provided by the Visual Studio property files. These issues appear to be the result of the main FILTERS development not being tracked in the Windows side of things.
