	Force alignment on OBJ_ATTRs
	</div>
	As of devkitARM r19, there are new rules on struct alignments, which means that structs may not always be word aligned, and in the case of `OBJ_ATTR` structs (and others), means that `struct` copies like the one in `oam_update()` later on, will not only be slow, they may actually break. For that reason, I will force word-alignment on many of my structs with `ALIGN4`, which is a macro for `__attribute__((aligned(4)))`. For more on this, see the section on [data alignment](bitmaps.html#ssec-data-align).
