	   Sure it will.  The imagebits are then just piled in right next to each other,
   as they say "imagebits are imagebits"...  ;-)

Suppose you have a 1-bit depth bitmap.  With a byte-granular quantity
(i.e., line_len, etc.), how can you specify a non-byte-aligned
subbitmap?  You can't.  So if you want to support subbitmaps you have
to use pixel offsets, not byte offsets, which isn't as simple.
