This tells big endian systems that the data is in ABGR instead of RGBA. It should be ignored on little endian systems! Add support in Amiga platform code. -> All platform code that could be compiled for big endian systems will need to be updated to recognise BITMAP_ABGR. This includes GTK and Framebuffer frontends. Both BITMAP_ABGR *and* the endianness of the host will most likely need to be checked and the allocated bitmap format and/or bitmap plotter changed to handle ABGR component order. svn path=/trunk/netsurf/; revision=9108
