https://bugs.webkit.org/show_bug.cgi?id=33287

           Summary: PNGEncoder.cpp lacks support for libpng 1.4
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Trivial
          Priority: P5
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jbowler at acm.org


Certain NULL macros were removed from png.h between 1.2 and 1.4, this patch
fixes it (you probably want to use your favourite NULL definition, not 0).
