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