[Spice-devel] [common PATCH 2/9 v4] pixman_utils: Add macros for color byte ordering

[Lukas Venhoda]

When using image compression on PowerPC architecture, colors are in
wrong order ARGB -> BGRA.

This commit introduces macros, that will change the color order
according to machine endianness.

Theese macros are similar to QEMU macros in qemu-pixman.h
