ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

f50dafa8fc vp3: avoid buffer overread in coeff decode 
I couldn't measure it to be slower for normal interframe videos.
For the worst case, high-bitrate intra-only videos, it can be 0.7% slower.

DECLARE_ALIGNED macro instead.

c72625f299 Delay translating DCT tokens into coefficients until immediately before IDCT 
This is generally around 12% faster than the prior method of creating a
linked list for each block as tokens are read, but can be anywhere from
8% to 28% faster depending on file and CPU.

7a095ea6fb Do MC and IDCT in coding (hilbert) order 
This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.

This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.

a89264761f Handle Theora's continued runs in superblock coding. 
This doesn't really matter yet since 4:2:0 1080p has only 3060 superblocks,
but larger resolutions or 4:4:4 1080p could hit this case.

33dbc1b7ca Use memset to set the runs partially coded superblocks 
Much faster for long runs (e.g. nearly uncoded frames), slightly faster
for the general case.
