Release 1.7.14 (1 May 2017) -- compared to 1.7.13

• oiiotool expression substitution now recognizes FRAME_NUMBER and FRAME_NUMBER_PAD. #1648
• oiiotool -resize and -resample now have more intuitive behavior for images where the display and pixel data windows are not the same, especially if the data window had a nonzero origin (such as with crop or overscan). #1667
• oiiotool --resample and ImageBufAlgo::resample() have been extended to work for "deep" images. #1668
• ImageCache::get_image_info() will now return a proper error (and not hit an assertion) if asked for information about a subimage or MIP level that does not exist in the file. #1672
• ImageBuf copy constructor from another ImageBuf was previously broken for IB's that wrap application buffers. #1665
• TextureSystem::get_texels fixes crashing behavior. #1669
• Fixes to OSX rpath behavior of linked binaries. #1671
• OpenEXR file input: fixed problem with sorting order of spectral alpha channels (RA, GA, BA, or AR, AG, AB). #1674
• ImageBufAlgo::deep_merge() (and oiiotool --deepmerge) now will give a useful error message if you try to merge two deep images that do not have the same number of channels. #1675
• ImageCache/TextureSystem statistics no longer list as "BROKEN" files which were invalidated, or files that were initialized with an ImageCacheFile but never opened. #1655
• Fix Windows warnings about SIMD types as function args, and about int vs bool. #1659
