12ec204ec7 moved ALIGN_CST into util/utils.h and renamed WEBP_ALIGN_xxx
Note that ALIGN_CST is still kept different in dec/frame.c for now,
because the values is 31 there, not 15. We might re-unite these two
later.

82d980209b add a dec/common.h header to collect common enc/dec #defines
had to rename few structs.

-> we can now include both vp8i.h and vp8enci.h without naming
conflicts.

f691f0e461 simplify VP8IteratorSaveBoundary() arg passing
we only need to save yuv_out_, so no need for the arg

93402f02db multi-threaded segment analysis
When -mt is used, the analysis pass will be split in two
and each halves performed in parallel. This gives a 5%-9% speed-up.

This was a good occasion to revamp the iterator and analysis-loop
code. As a result, the default (non-mt) behaviour is a tad (~1%) faster.

733a7faae4 enc->Iterator memory cleanup
* move yuv_in_/out_* scratch buffers to iterator
* add y_top_/uv_top_ shortcuts in iterator

That's ~3k of stack size instead of heap.
But it allows having several iterators work in parallel.

d640614d54 update copyright text
rather than symlink the webm/vpx terms, use the same header as libvpx to
reference in-tree files

f2cee06708 Fix floating point exception with cwebp -progress
Adds a test of enc->mb_h_ to VP8IteratorProgress() to avoid a division
by zero. Fixes issue #121.

Original patch from even rouault (even dot rouault at gmail dot com).

f18281ffa0 WebPReportProgress: use non-encoder specific params
Take picture and percent value storage location instead of VP8Encoder.
This will allow reuse by the lossless encoder.

f8db5d5d1c more C89-fixes
going down to strict -ansi c89 is quite overkill (no 'inline',
and /* */-style comments).
But with these fixes, the code compiles with the stringent flags:
 -Wextra -Wold-style-definition -Wmissing-prototypes
 -Wmissing-declarations and -Wdeclaration-after-statement

f61d14aabf a WebP encoder
converts PNG & JPEG to WebP

This is an experimental early version, with lot of room
of later optimizations in both speed and quality.

Compile with the usual `./configure && make`
Command line example is examples/cwebp

Usage:

   cwebp [options] -q quality input.png -o output.webp

where 'quality' is between 0 (poor) to 100 (very good).
Typical value is around 80.

More encoding options with 'cwebp -longhelp'
