Release 1.7.13 (1 Apr 2017) -- compared to 1.7.12

• TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it does a better job of discerning the proper data types. #1627
• RAW: The default value for missing "raw:use_camera_matrix" has been changed to 1 (not 0) to better match default behavior of libraw/dcraw. #1629
• RAW: Add support for selecting new demosaicing algorithms: "DMT" (mode 11) and "AAHD" (mode 12). Renamed the "Modified AHD" to "AHD-Mod" to simplify and match libraw terminology. Made matching of demosaicing algorithms case-insensitive. #1629
• RAW: Support "ACES" color space for direct conversion while reading RAW images (supported in libraw 0.18 or newer). #1626
• oiiotool: Improved error reporting of file open errors when -iconfig is used. #1626
• oiiotool --echo STRING prints the string to the console. This can contain expressions! So you can do something like oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}" #1633
• JPEG: Be more reslient to malformed Exif data blocks with bogus offsets. #1585, #1639
• TIFF output omitted setting the "Make" and "Model" metadata tags. #1642
• webp: Several new sanity checks prevent the webp reader from spending too much I/O time and memory reading bogus files (malformed, corrupted, or not a webp after all). #1640
• PSD: Support has been added for "cmyk", "multichannel", and "grayscale" color modes. And support was fixed for rgb and grayscale 32 bit per sample bit depth. #1641
