------- Additional Comments from Adam Roben <aroben at apple.com>

	Part of http://bugs.webkit.org/show_bug.cgi?id=16133
	<rdar://5071708>

	Reviewed by NOBODY (OOPS!).

	* DumpRenderTree/cg/PixelDumpSupportCG.cpp: Added.
	(printPNG): Dumps a CGImageRef as a PNG to stdout, along with a
	Content-Length header.
	(getMD5HashStringForBitmap):
	(dumpWebViewAsPixelsAndCompareWithExpected):
	* DumpRenderTree/cg/PixelDumpSupportCG.h: Copied from
WebKitTools/DumpRenderTree/mac/DumpRenderTreePasteboard.h.
	* DumpRenderTree/win/DumpRenderTree.cpp:
	(dump): Do a pixel dump if requested.
	(main): Parse pixel test options.
	* DumpRenderTree/win/DumpRenderTree.vcproj: Added new files and added
	the cg/ subdirectory to the include path.
	* DumpRenderTree/win/MD5.cpp: Added. Windows MD5 functions aren't
	available in a header or import library, so we have to go through this
	LoadLibrary/GetProcAddress dance to use them.
	(cryptDLL):
	(init):
	(update):
	(final):
	(MD5_Init):
	(MD5_Update):
	(MD5_Final):
	* DumpRenderTree/win/MD5.h: Added.
	* DumpRenderTree/win/PixelDumpSupport.h: Added. This file should be
	moved up to the top level to share it with Mac eventually.
	* DumpRenderTree/win/PixelDumpSupportWin.cpp: Added.
	(getBitmapContextFromWebView): Forces the WebView to paint using a
	WM_PRINTCLIENT message, and puts the result in a CGBitmapContext.
