36 * This thumbnail caching implementation attempts to conform
37 * to the Thumbnail Managing Standard proposed on freedesktop.org
38 * The standard is documented here:
39 * http://triq.net/~jens/thumbnail-spec/index.html
40 * (why isn't it actually hosted on freedesktop.org?)
42 * This code attempts to conform to version 0.7.0 of the standard.
45 * > Validation of the thumb's embedded uri is a simple strcmp between our
46 * version of the escaped uri and the thumb's escaped uri. But not all uri
47 * escape functions escape the same set of chars, comparing the unescaped
48 * versions may be more accurate.
49 * > Only Thumb::URI and Thumb::MTime are stored in a thumb at this time.
50 * Storing the Size, Width, Height should probably be implemented.
