This series re-introduce the line-by-line algorithm. This is simpler than the read part because no rotation/translations are involved. PATCH 1/3 is the re-introduction itself PATCH 2/3 is a proposition to avoid code repetition using a "big" macro. PATCJ 3/3 is the usage of PATCH 2 to support a new format This series depends on [1].
