pdiff: Compile pdiff algorithm as a libtool convenience library The convenience library provides a pdiff_compare function with a cairo interface into the perceptual diff algorithm. 2006-12-12 16:49:27 -08:00			`/*`
pdiff: Re-indent all code I've given up on trying to preserve the old code formatting for compatibility. We're not planning on augmenting the algorithm itself, just integrating it into cairo. So I don't expect to make changes that we'll be all that interested in pushing upstream. 2006-12-13 18:08:25 -08:00			`Copyright (C) 2006 Yangli Hector Yee`
