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

(cherry picked from commit d640614d54)
They went out of sync some time ago, and are
no longer really required since we have them
buildable from makefile.unix

(cherry picked from commit a4e1cdbbe8)
buffer the last frame's details to perform DISPOSE_BACKGROUND on the
image's area, rather than the entire canvas.
also fixes transparent backgrounds with animated images

* fix gif2webp to handle disposal method and odd offset correctly
+ remove -scale and -crop option from vwebp, since it'll be broken
with offsets and fragments. Needs a revisit.
+ remove a warning in gif2web

- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.

- 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.
Change-Id: If0b229ad9fce296372d961104aa36731a3b1304b
'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
Change-Id: Id49e87c26628c2b58ec221f6030cbd2e46a807b4
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.
