Christophe Gisquet	9fa056ba75	pngdsp x86: use unaligned access For test images manually generated to contain only up prediction, timing results: 8380x3032 255x185 before: 138635 1992 after: 139232 1996 Actually jumping to the proper version depending on the alignment: 8380x3032: 138767 A 0.5% speed improvement for gigantic images is not worth the code duplication.
