- WEBP_MUX_INVALID_PARAMETER: was used only at one place, and that too
should actually be an assert().
- WEBP_MUX_ERROR: was never used.

- Match offsets, duration, width/height for frames/tiles and enforce
some constraints.
- Note that this also means using 'int's instead of 'uint32_t's for
16-bit and 24-bit fields.

the extended file format is still under development and related
libs/binaries are not fit for release
configure:
--enable/disable-libwebpmux; default is disabled.
makefile.unix:
src/mux/libwebpmux.a and examples/webpmux must be explicitly specified
Makefile.vc:
$(DIRLIB)\libwebpmux.lib and $(DIRBIN)\webpmux.exe must be explicitly
specified

* add a real proper pointer for holding memory chunk pointer
(instead of using y and argb fields)
* polish the doc with details
* add a WebPPictureView() that extract a view from a picture
without any copy (kind of a fast-crop).
* properly snap the top-left corner for Crop/View. Previously,
the luma position was not snapped, and was off compared to the chroma.

'Set' and 'Get' methods for images take/return a bitstream as input,
instead of separate 'image' and 'alpha' arguments.
Also,
- Make WebPDataCopy() a public API
- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.

- Move TAG_ID to webp/mux.h
- Rename it to WebPChunkId
- Rename IDs to WEBP_CHUNK_<tag>
- Remove "name" param from ChunkInfo struct and related changes.
- Rename WebPMuxNumNamedElements to WebPMuxNumChunks().
- WebPMuxNumChunks() takes WebPChunkId as param.

Since
437999f introduce a generic WebPPictureHasTransparency() function
lossy encodes will not encode alpha if the alpha channel is completely
opaque.
Change-Id: I1826669c3932483650d7f8ce806cfebd4e5225fc
VP8-lossy will now avoid writing an ALPH chunk if the
alpha values are trivial.
+ changed DumpPicture() accordingly in cwebp
+ prevented the -d option to be active with lossless
(DumpPicture wouldn't work).

Fixes issue #115.
Define local copies of GUID_WICPixelFormat24bppRGB &
GUID_WICPixelFormat32bppRGBA (and GUID_WICPixelFormat32bppBGRA for
symmetry) to avoid link issues when building against older versions of
the SDK.

it's using glutTimerFunc() for trigger next frame's decoding
Reminder: how to build and use manually (integration in makefile.unix coming soon)
Unix:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -framework GLUT -framework OpenGL -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a
Mac + xcode:
cd libwebp

- remove some unused functions
- move global arrays from data to read only section
- explicitly cast malloc returns; not specifically necessary, but helps
show intent
- miscellaneous formatting
Change-Id: Ib15fe5b37fe6c29c369ad928bdc3a7290cd13c84
Add WebPDataCopy and use it in ReadImage which now returns WebPData*s.
Update ReadData prototype variables used with it to avoid unnecessary
const casting back and forth from void*.
