[PATCH] remove some FZIGZAG
Hello,
As we discussed with derf some time ago, it seems it is not neccessary to enforce "forward" order of dct_coeffs.
This patch gains .99366902855226196000% so approx 1% speedup.
Meausurement method:
time nice -n -19 ./dump /mnt/disc4/theora/unix/gripen.ogg > /dev/null
Ogg logical stream 310b2968 is Theora 720x480 29.97 fps video
Encoded frame content is 720x480 with 0x0 offset
