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