#234 Fix BUS Error due to gld_drawinfo.data alignment

[canavan]

The following patch is required on platforms that do not allow unaligned accesses (e.g. MIPS, IA64, some ARM) to prevent BUS Errors when accessing sprite->flags and possibly other objects in gld_drawinfo that require alignment on 8 byte boundaries. Usually, malloc() would take care of the alignment requirements, but that's not possible here due to the different alignment requiremtns of the various types stored in gld_drawinfo.data.

does it work now? (i replaced sizeofs with SIZEOF8 macro)
