Gautam Ramakrishnan 995d937827 libavcodec/jpeg2000: fix precinct coordinate calculation 
The calculation of precinct boundaries has been
fixed. The precinct boundaries were calculated
as an offset to the band boundary, but must
instead be calculated as an offset from the
reslevel. This patch fixes #4669 and #4679.
