From Mozilla x86-64

To improve x64 build, I recognize the following items.

Cairo (pixman) improvement

Although x86 build can use MMX optimization for pixman, x64 build is disabled. Becasue Microsoft Compiler cannot generate MMX code. Upstream pixman has SSE2 optimization like the following.

Add SSE2 implementations of many compositing operations.

configure.ac
pixman/pixman-pict.c
pixman/pixman-sse.c
pixman/pixman-sse.h

But this cannot use it on Windows x64 because it uses MMX for unalignment access. You know, Microsoft C Compiler doesn't support built-in MMX functions.

So, I made a new patch to remove MMX, then I added for this improvement to Firefox 3.1 (and later) build. See pixman-sse2 patch in http://hg.mozilla-x86-64.com/firefox31-win64-mq/. After I clean up this, I will post it to cairo-dev.

NSIS (Nullsoft Software Installer)

NSIS is 32bit binary. I need port NSI. System plugin is native API wrapper, I need port this from scratch.
