Bug 692805: BBox rounding issues
Currently all conversions from rect to bbox are done using a single
function, fz_round_rect. This causes problems, as sometimes we want
'round, allowing for slight calculation errors' and sometimes we
want 'round slavishly to ensure we have a bbox that covers the rect'.
We therefore split these 2 cases into 2 separate functions;
fz_round_rect is kept, meaning "round outwards allowing for slight
errors", and fz_bbox_covering_rect is added to mean "give us the
smallest bbox that is guaranteed to cover rect".
No regressions seen.
