HOSTTYPE is x86_64 on e.g.,
bash 3.2.48(1)-release
ProductName: Mac OS X
ProductVersion: 10.6.7
BuildVersion: 10J869
intel-mac seems to be the value under tcsh.

When WEBP_HAVE_(JPEG|PNG) were undefined the stub functions would
produce warnings for unused parameters.

You can now use WebPDecBuffer, WebPBitstreamFeatures and WebPDecoderOptions
to have better control over the decoding process (and the speed/quality tradeoff).
WebPDecoderOptions allow to:
- turn fancy upsampler on/off
- turn in-loop filter on/off
- perform on-the-fly cropping
- perform on the-fly rescale
(and more to come. Not all features are implemented yet).
On-the-fly cropping and scaling allow to save quite some memory
(as the decoding operation will now scale with the output's size, not
the input's one). It saves some CPU too (since for instance,
in-loop filtering is partially turned off where it doesn't matter,
and some YUV->RGB conversion operations are ommitted too).
The scaler uses summed area, so is mainly meant to be used for
downscaling (like: for generating thumbnails or previews).
Incremental decoding works with these new options.
More doc to come soon.
dwebp is now using the new decoding interface, with the new flags:
-nofancy
-nofilter
-crop top left width height
-scale width height

Rather than %include'ing decode.h and potentially pickup new
(unsupported functions), explicitly list the desired functions as with
encode.
Reorganize a bit to contain most of the language specific additions to
one area. This fixes the visibility of the wrap_* functions in java. The
method modifiers need to come before the function prototypes.

This is a temporary workaround for issue #80.
Currently dec/dsp_sse2 is not included in Makefile.vc. Simply adding it
will cause a build error, however, as cl does not support aligning
function parameters producing, e.g.,
src\dec\dsp_sse2.c(228) : error C2719: 'q1': formal parameter with
__declspec(align('16')) won't be aligned

Wrap WebPEncode???* to provide an interface similar to decode.
As only WebPGetEncoderVersion is wrapped directly from encode.h avoid
including it in the swig file to reduce %ignore's.
This change also removes unnecessary incremental decoding related enums.

There was 1 unneeded sample line allocated for the filter cache in of simple filtering.
+ Add an explaining comment.

Replace usage of _WIN32 in examples as this does not guarantee the
presence of wincodec.h.
mingw-w64 notably includes wincodec.h, though other releases do not.
Under cygwin the following can be used for a WIC enabled binary:
./configure --target=i686-pc-mingw32 CC=i686-w64-mingw32-gcc.exe

Only builds with --enable-experimental require zlib currently.
A base install of mingw will not include the development headers and
library. libwebp itself will now build in such environments.
Additionally, remove -lz from **/Makefile.am, -lz will be added to LIBS
by AC_CHECK_LIB when necessary.

Use _MSC_VER as the intrinsics compile without /arch:SSE2 on x86.
Also avoids applying the same flag to all files which defeated the
purpose of the runtime cpu-detection.
Thanks to Frank B. for the suggestion!

picture->error_code can be looked up for finer error diagnose.
Added readable error messages to cwebp too.
Should close bug #75 (http://code.google.com/p/webp/issues/detail?id=75)

Allows clean to target a specific CFG output directory which has the
side benefit of supporting of tree builds.
Earlier versions would clean the entire source tree possibly removing
multiple builds.

Currently only supports a subset of decode functions and likely only
works fully for java.
For java bindings:
The generated java source can be compiled and the class files added to
libwebp.jar.
The generated jni source can be compiled to, e.g., libwebp_jni.so, which
can then be loaded via System.loadLibrary("webp_jni").

sometimes, gcc insert sse2 storeu instructions (like in VP8InitFilter())
with aligment requirements.
Bug was visible 'sometimes' in non-debug mode, when trying to use -af.
