In fact, I *am* sure of what I'm doing, since the original rows are 
obviously 4-byte aligned, and for 1 bpp to 8 bpp conversion the row 
alignment of the 8 bpp data will be 8 * 4 = 32 bytes. The question is 
whether the overhead of using 32-byte rather than 16-byte alignment is 
acceptable. I suppose it is. It only concerns 1, 2 and 4 bpp files.
