[cairo] End to end turn key build instructions for Win32

[Travis Griggs]

I've finally finished the win32 companion to the osx build  
instructions I put up on the wiki. As before, feedback appreciated.

http://cairographics.org/end_to_end_build_for_win32/

It builds a standalone dll, that requires no other dll's or specific  
versions of Windows. We've tested it on W2K thru W7. Doing so makes it  
about 25% bigger than the alternative.

The trickiest part of doing this, was not actually pixman or cairo,  
but rather zlib and libpng. Hats off to those that worked on the  
Windows build system a year or so ago.
