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