Remove CPU detection code.
Move CPU detection code out of the MMX file and into the generic code to avoid compiling it with -mmmx and -msse. Using these options causes gcc to use MMX and SSE instructions in the CPU detection code which causes SIGILLs on older processors.
Portability improvements for win32 thanks to Hans Breuer <hans@breuer.org>:
Defined sized-integer types when under the influence of _MSC_VER and without stdint.h.
Use #error which is more portable than #warning, (and more indicative of where we want to be before the next release).
Add an fbpict.c ported from the latest in xserver/fb, including hooks to the MMX code where appropriate. This replaces the old ic.c file.
Replaced by fbpict.c.
Move some X server macros from fbpict.c up into icint.h to keep the diff small.
Add fbmmx and fbpict.c, remove ic.c.
Add a check for the MMX intrinsics. gcc >= 3.4 is required.
Remove iccompose.c, replaced by fbcompose.c.
Add a slightly-trimmed version of fbpict.h from xserver/fb to make the port smaller and cleaner.
Use the redundant fbpict.h defines and add in the struct for indexed colour support.
Remove defines now in fbpict.h.
Add some constants and types required by fbcompose.c
Add fbcompose.c and fbpict.h, remove iccompose.c.

Build pixman internally as a private part of cairo, with suitable name changes to avoid any visible pixman symbols in the cairo library:
Descend into pixman.
Drop libpixman from Requires.
Don't check for libpixman. Check version of pkg-config and use Requires.private instead of Requires in cairo.pc if possible. Generate pixman Makefiles.
Rip out release-publish target and installation of libpixman.pc.
Add pixman-remap.h. Drop libpixman.la target.
Fix to include config.h rather than ../config.h
This is the cpp magic to rename all pixman functions from the various fb, Fb, INT_pixman, pixman, Render, _Render, or no prefix to _cairo_pixman_ prefixes.
Include pixman-remap.h to get all the cairo-internalized names.
Add -Ipixman/src to get at pixman-remap.h.
- fbCombineSaturate was pointed at fbCombineDisjointOver, instead of fbCombineDisjointOverReverse as it should. Instead, point fbCombineDisjointOverReverse at fbCombineSaturate (which is likely to be faster).
- fix previously-unused fbCombineSaturate implementation.
- fbCombineMaskAlphaC was just a copy of fbCombineMaskValueC. Make it do what it's supposed to (return a cs.alpha).
- fbCombineAtopC didn't invert the source alpha value.
- fix copy'n'paste errors in fbCombine(Dis/Con)jointGeneralC, also source alpha wasn't treated in a component fashion.
From anholt.
The code comes from keithp: Initial import of Composite extension along with name change from Apportion. Added some accelerated code to fbpict to make this initial hack a bit faster. "real" extension bits to follow.
