might as well put it in the appropriate file.

6524fcd614 vwebp_sdl: simple viewer based on SDL 
Uses WebPToSDL() generic function defined in vwebp_sdl.[ch].
This function is not included in the libextras library, because it
would bring in an SDL dependency. Probably too heavy for now.

WebPToSDL() is separate, because it will be called used by the javascript
version of libwebp (through emscripten build rules)

03f40955a3 img2webp: convert a sequence of images to an animated webp 
Usage:

  img2webp [file-level options] [image files...] [per-frame options...]

File-level options (only used at the start of compression):
 -min_size ............ minimize size
 -loop <int> .......... loop count (default: 0, = infinite loop)
 -kmax <int> .......... maximum number of frame between key-frames
                        (0=only keyframes)
 -kmin <int> .......... minimum number of frame between key-frames
                        (0=disable key-frames altogether)
 -mixed ............... use mixed lossy/lossless automatic mode
 -v ................... verbose mode
 -h ................... this help

Per-frame options (only used for subsequent images input):
 -d <int> ............. frame duration in ms (default: 100)
 -lossless  ........... use lossless mode (default)
 -lossy ... ........... use lossy mode
 -q <float> ........... quality
 -m <int> ............. method to use

example: img2webp -loop 2 in0.png -lossy in1.jpg
                  -d 80 in2.tiff -o out.webp
