[cairo] Release candidate for 1.4.12 (testing requested!)

Hi Carl,

The problems are in:

pixman/src/fbcompose.c
pixman/src/icimage.c
pixman/src/pixregion.c

None of these files include cairo-wideint-private.h directly or
indirectly.

Upon closer inspection the single source of the problem are the three
_pixman_malloc_ab... macros defined in pixmanint.h, which use the
undefined INT32_MAX.

Copying the definition of INT32_MAX from cairo-wideint-private.h to
pixman.h (seems appropriate, as UINT16_MAX and UINT32_MAX are also
defined there) solves the compilation problem.
