- 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.

'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.

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
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -lglut -lGL -lpthread -lm -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a

Quite handy and simple (for now).
It's not yet incorporated within the build system (autotools or
makefile.unix), because it gets complicated with OpenGL. TODO(later).
For now, there's some ready-to-use command line for compiling on Linux
or Mac in the header of vwebp.c
Later, this tool will be supplemented with support for animation,
tiling, zooming, etc.
