=================

there's a decoding example in example/dwebp.c which will take a .webp file and

decode it to a PPM image file. This is simply to demonstrate use of the API.

decode it to a PNG image file. This is simply to demonstrate use of the API.

It also decodes to PPM (or even PGM) format.

You can verify the file test.webp decodes to exactly the same as test_ref.ppm:

`cd examples && ./dwebp test.webp -o test.ppm && diff test.ppm test_ref.ppm`
