[webkit-dev] WebCore.vcproj Debug_Cairo config appears to be broken...

Upon sync-ing WebKit on Windows/Cygwin, I get this build error for 

    ..\loader\CachedImage.cpp(38) : fatal error C1083: Cannot open 
include file: 'PDFDocumentImage.h': No such file or directory

This appears to be due to a bug in WebCore.vcproj or a mistake in the 
source code's usage of PDFDocumentImage.h. Rationale follows:

The error corresponds to this code from CachedImage.cpp:

    #if PLATFORM(CG)
    #include "PDFDocumentImage.h"

Platform CG is unilaterally defined in config.h via this:

    #define WTF_PLATFORM_CG 1
    #define WTF_USE_CFNETWORK 1
    #undef WTF_USE_WININET
    #define WTF_PLATFORM_CF 1
    #define WTF_USE_PTHREADS 0

The PDFDocumentImage.h file is in fact present in the 
WebKit/WebCore/platform/graphics/cg directory.

However, WebCore.vcproj doesn't list that directory in its set of 
include directories for the Debug_Cairo config. It instead has the 


Thus such a compiler error occurs because PDFDocumentImage.h is not 
visible to the vcproj in the Debug_Cairo config. The Debug config 
doesn't have this problem, as it has the cg directory visible.

Of course, this all might be due to the Debug_Cairo config not being 
supported, though I can't find anything saying this is so and 
Debug_Cairo happens to be the default config when you first open the 
WebKit.sln file.
