I tried this patch, but it does not produce the rotated images.
The problem is that the record* tests clip the rendering in many
2x2 rectangles, in that situation the scan-converter hardly executes
full_row, mainly sub_row (in every row there is a new or end edge)
and my idea above (offsetting half of a subrow) works in that case,
but it breaks the more general fullrow case in which that offset is
not necessary/correct.</pre>
