OPJ_BOOL opj_t1::encoder
opj_flag_t* opj_t1::flags

Flags used by decoder and encoder.

Such that flags[1+0] is for state of col=0,row=0..3, flags[1+1] for col=1, row=0..3, flags[1+flags_stride] for col=0,row=4..7, ... This array avoids too much cache trashing when processing by 4 vertical samples as done in the various decoding steps.
