These configurations will produce a dll in bin/ and an import lib under
lib/.
Currently the -noasm switch in the examples will be disabled for these
builds due to a dependency on VP8EncGetCPUInfo.

Add WEBP_EXTERN(type) macro which should make Windows DLL builds simpler
by allowing the signature to be changed.

RGB565 and ARGB4444 are only supported through the advanced decoding API.
ARGB being somewhat generic, there's an easy WebPDecodeARGB()
new function for convenience.

Rather than add bulk to test for the new flag, simply comment out -Wvla
to keep the base makefile simple.
-Wvla was added in gcc-4.3.0.

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.

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.
