But if you have, say, a 299x645 memory bitmap, then the line[] pointers won't
be 16-byte aligned. You could get around this by making the bitmap pitch
((w*bytes_per_pixel + 15) & ~15), but I'm sure some programs will break if
there's space between the end of line[x] and the beginning of line[x+1].
And also, you can't gaurantee the alignment of video bitmaps, can you?
